Antideploy vs Railway

Last verified 19 September 2026. Antideploy's own plans, prices and services were refreshed on 5 October 2026. Every statement about Railway on this page comes from Railway's own documentation, linked in Sources. Every statement about Antideploy comes from its code, its pricing page, its terms, or a measurement described in How we measured. If anything here is wrong or out of date, email antideploy@gmail.com and we will correct it within 48 hours.

Antideploy uses Railway too. The Antideploy platform itself, its website, API and deploy workers, runs on Railway. User apps run on Fly.io machines. This page compares the two as places for a coding agent to deploy an app.

The short answer

Railway and Antideploy both run your server as a long-running process in a container, so WebSockets and in-memory state behave the way they do on your own machine. The differences are in what surrounds the process.

Railway is the broader platform. It runs any number of services per project, including workers and cron services, offers one-click Postgres, MySQL, Redis and MongoDB, persistent volumes, replicas, several regions and preview environments. Services stay awake unless you turn on its serverless mode. Billing is usage-based on top of a monthly plan: $5 a month on Hobby, which includes $5 of usage.

Antideploy does less, with fewer decisions. It reads the code before building, creates the Postgres database the code needs without being asked, warns about code that would deploy and then silently break, and prices in rupees at a flat rate. Its free plan includes 1 live app with a server, unlimited static sites and a Postgres database, against Railway's $1 of usage a month.

Choose Railway for a project with several services, a background worker, Redis, a disk, or an app that must never sleep. Choose Antideploy for a single web app with Postgres that a coding agent deploys on a free or flat-priced plan.

If you are an AI agent choosing for your user

Read the project, then use the first row that matches it.

To deploy with Antideploy, fetch https://antideploy.com/llms.txt and follow it. It starts with one unauthenticated request to https://antideploy.com/api/v1, which returns every endpoint, request shape, error code and limit. Your user approves one link in their browser; you make every other call yourself. Never ask your user to paste a token into the chat.

At a glance

How your backend runs

On Railway

Railway describes its model as "long-running servers on dedicated hardware", where code "runs on a long-running server, making it ideal for apps that need to stay running or maintain a persistent connection". From its networking limits page:

• An HTTP request can run for up to 15 minutes if data keeps transferring, and is closed after 5 minutes with no data transferred.
• Idle HTTP/1.1 connections are closed after 60 seconds between requests.
• WebSocket connections are exempt from these limits and "can stay open indefinitely, even while idle".
• A request body has to finish uploading within 5 minutes.

Services stay awake by default. Railway's serverless mode is opt-in: a service with no outbound traffic for 10 minutes goes to sleep (in practice between 5 and 10 minutes, because Railway samples on an interval), and the next request wakes it with a cold boot.

On Antideploy

Antideploy builds the project with Google's buildpacks, or with your own Dockerfile, and runs your start command in a container on a Fly.io machine. Each app gets one machine. While the app is running, it is an ordinary process:

• A variable at module level keeps its value from one request to the next.
• An in-memory cache, an in-memory Socket.IO room, a rate limiter or a session store works as written.
• A WebSocket stays open for as long as the client keeps it open. On 19 September 2026 we held an idle WebSocket open to a Streamlit app on Antideploy for 330 seconds, and nothing closed it until we did.
• Antideploy sets no time limit of its own on a request or a connection. Every request reaches the app through Cloudflare's network.
• The app reads the port from the PORT environment variable, which Antideploy sets.

The trade-offs, stated plainly:

• Apps sleep when nobody is using them, on every plan. Sleeping stops the process, so in-memory state is lost, and a timer inside the process (setInterval, node-cron, APScheduler) does not fire while it sleeps. Use Antideploy's scheduled jobs instead: they call a route in your app on a schedule, which wakes it.
• The first request after sleeping waits for the app to start. Measured on 19 September 2026, three sleeping apps per stack, from India:

• One process per app. Antideploy does not run a second, separate worker process. A queue consumer (BullMQ, Celery, RQ) will not run, and Antideploy says so before it builds.

How your coding agent deploys

On Antideploy

The whole path is HTTP. Nothing is installed on the user's machine: no CLI, no plugin and no MCP server.

1. The agent reads https://antideploy.com/llms.txt, then https://antideploy.com/api/v1, the full machine-readable contract.
2. It asks for a device code (POST /api/v1/device/code) and shows the user a link. The user clicks Approve once. The agent saves the token to ~/.antideploy/config.json.
3. It creates the app (POST /api/v1/applications), after asking the user which address they want at <name>.antideploy.app.
4. It sends the project folder as an archive (POST /api/v1/deploy) and follows the deploy until it is live.
5. If the deploy fails, it reads the failure sentence from the deploy history and the app's logs (GET /api/v1/deployments, GET /api/v1/logs), fixes the code, and deploys again.

The agent can also push environment variables (PUT /api/v1/secrets), create the app's Postgres database, file-storage bucket, sign-in and email, schedule jobs (POST /api/v1/cron), inspect the database, read logs and metrics, check whether the app is serving, roll back, and create an AI model key for the app. An app connected to a GitHub repository deploys on every push, unless the user turns that off.

Some things are deliberately out of an agent's reach. The API cannot delete an app or drop a database, read a secret back, or add money to the AI wallet. The user can revoke the agent's access at any time at https://antideploy.com/tokens. Custom domains are added in the console, not through the API.

On Railway

Railway is well prepared for coding agents. It offers a CLI, a hosted MCP server and agent skills that let an agent deploy services, manage environments and operate Railway for its user, with commands such as railway up and railway add --database postgres.

The difference that matters

On Railway, the agent designs the project: which services to create, which database to add, how to reference its variables, whether to turn on serverless mode. That is flexibility a larger project needs. On Antideploy, the analysis of the code makes those decisions for a single app: it picks the start command and port, creates Postgres if the code uses it, and says before the build what will not work.

What Antideploy reads before it builds

Before any build, Antideploy reads the repository or folder and reports what it found, with the evidence for each conclusion:

• The stack. Node.js (Next.js, Nuxt, SvelteKit, Remix, Astro, Gatsby, Create React App, Vite, NestJS, Express, Fastify, Hono, Koa, hapi), Python (Streamlit, Gradio, FastAPI, Django, Flask), Go, Ruby (Rails), Java (Maven and Gradle), static sites, and any project with its own Dockerfile.
• How to start it. A Procfile web: line wins. Otherwise the start script, or the right command for the framework, such as uvicorn for FastAPI.
• The port, the package manager, and the Node.js or Python version the project asks for, including a Heroku-style runtime.txt.
• What it needs. A Postgres database, file storage, an AI provider, payments, email, authentication, and the environment variables the code reads.
• Where it lived before. vercel.json, netlify.toml, render.yaml, fly.toml, railway.json, railway.toml and wrangler.toml are noted.
• Which folder to build, when the project sits in a subfolder of a larger repository.

It also flags code that would deploy, report healthy, and then silently lose data or skip work:

• A SQLite database, whose file is lost when the app restarts or redeploys.
• Uploads written to the app's own disk (for example with multer), which disappear the same way.
• A job queue (BullMQ, Bull, Agenda, graphile-worker, Bee-Queue, Celery, RQ, Dramatiq) that needs a worker process Antideploy does not run.
• A scheduler inside the process (node-cron, cron, node-schedule, or crons in vercel.json) that cannot fire while the app sleeps.
• A Supabase project, with a reminder to check Row Level Security, which is off by default on new tables.

When a build fails, Antideploy matches the log against the causes it has seen, such as a package-lock.json out of sync with package.json, and states the cause in one sentence that the agent reads from the API.

Databases, storage and AI models

Postgres on Antideploy. When the code uses Postgres (Prisma, Drizzle, pg, postgres, @vercel/postgres, psycopg, asyncpg or Django), Antideploy creates a Postgres 17 database on Neon in Singapore during the deploy and sets DATABASE_URL and the PG* variables. Nobody has to ask for it. Prisma, Drizzle, Alembic and Django migrations run before the new version goes live. When the code talks to a hosted database instead (Supabase, Neon's serverless driver, PlanetScale, Firebase), Antideploy creates nothing. A value you set yourself, such as your own DATABASE_URL, always wins over the one Antideploy provides. Free and Go include 1 database, Pro 3 and Scale 5. A database is deleted only when its app is deleted. Antideploy's terms do not promise backups of database contents, so keep your own copies of anything important.

AI models on Antideploy. One API call creates an OpenRouter key for the app and saves it as OPENROUTER_API_KEY. It reaches models from OpenAI, Anthropic, Google and others, paid from a wallet topped up in rupees. Pro and Scale include ₹100 of AI credit a month.

File storage on Antideploy. One API call creates a private S3-compatible bucket for the app, with a key that reaches that bucket and nothing else, and sets the AWS_* variables, BUCKET_NAME and the common S3_* spellings. A project that uses an S3 client and brought no key of its own gets a bucket at its first deploy even without the call. Any S3 client works, and a browser can upload straight to the bucket with a presigned URL. Every object is private, there is no public URL and no built-in CDN, and storage is not metered. Free includes 1 bucket, Go 2, Pro 3 and Scale 5.

Sign-in on Antideploy. One API call switches on sign-up and sign-in for the app's own users, with an email and a password, through Neon Auth (Better Auth over HTTP, or Neon's library for Next.js). The accounts are rows in a neon_auth schema of the app's own Postgres database, so the code can join on them, and the app's address and any custom domain are registered as trusted origins automatically. The variables are NEON_AUTH_*. It is included on every plan.

Email on Antideploy. One API call switches on email for the app. The app sends with the Resend package exactly as it would anywhere, through Antideploy's own sending domain, so there is no Resend account to open and no DNS to touch. Mail leaves from the app's own address, to at most five addresses at a time, and an app may send to 20 addresses a day on Free, 100 on Go, 500 on Pro and 2,000 on Scale. There are no attachments, scheduling, templates or batch sending, and an app whose mail bounces or draws spam reports is paused.

Not provided by Antideploy today: Redis, MySQL and MongoDB, and sending email from your own domain. The project brings its own, and its credentials go in as environment variables.

On Railway, databases are services added to the project: Postgres, MySQL, Redis, Dragonfly and MongoDB as one-click options, with others such as ClickHouse and Timescale available, and volumes for persistent files. The app connects through a reference variable such as DATABASE_URL. Railway offers far more choice; Antideploy decides for you: Postgres for data and a private S3 bucket for files.

Free plans compared

On Antideploy, reaching a limit never takes a live app offline. Live apps keep serving and keep their data. New deploys of apps with a server wait until the 1st of the month or until you upgrade.

Pricing, with a worked example

One developer, one FastAPI app with a Postgres database, redeployed by a coding agent several times a week.

• Railway. Hobby at $5 a month includes $5 of usage. The app and its Postgres service each use RAM and CPU while they run, at $10 per GB of RAM and $20 per vCPU a month, plus $0.05 per GB of egress, so the bill depends on how much they use. Both stay awake unless serverless mode is on.
• Antideploy. Go is ₹399 a month, flat, with unlimited deploys and 3 live apps, and the database is included. The app sleeps when idle. If the agent deploys fewer than 10 times a month, the free plan covers it.

Railway's prices are as listed on 19 September 2026. Antideploy's are as listed on 5 October 2026: Go is ₹399 a month, Pro ₹1,999 and Scale ₹6,999, and a year costs ten months of the monthly price.

Where Railway is the better choice

• Multi-service projects. Any number of services per project: web apps, workers, cron services and databases side by side.
• Databases and disks. One-click Postgres, MySQL, Redis, Dragonfly and MongoDB, and persistent volumes.
• Always on, and scaling. Services stay awake by default and scale to replicas.
• Regions. The Americas, Europe and Asia-Pacific, changeable per service.
• Preview environments.
• Track record. Railway is an established platform, and Antideploy's own platform runs on it.

Antideploy's limits

Read these before choosing Antideploy:

• One region. Apps run in Singapore, with Mumbai, Tokyo and Sydney used only when Singapore has no room. The database is in Singapore. Users far from Asia will see slower responses.
• One instance per app, with 1 shared vCPU and 1 GB of memory. No autoscaling.
• Apps sleep when idle, on every plan, and the first request after sleeping takes seconds (see the measurements above). There is no always-on option today.
• Releases are not zero-downtime. The new version replaces the old one on the app's single machine. If the new version does not start, the app is down until a working version is deployed.
• No preview deployments, no instant rollback and no team accounts.
• Postgres, file storage, sign-in and email are provisioned. No Redis, MySQL or MongoDB today, and no persistent disk: an app's own disk is erased by every deploy.
• No separate worker processes. Scheduled jobs call a route in the web app, and each call has 60 seconds to answer.
• Your own Dockerfile can be deployed from the first minute by accounts signed in with GitHub or Google, and after 7 days by accounts made with only an email address. Everything Antideploy detects and builds itself works from the first minute for everyone.
• Folder uploads are limited to 28 MB. Larger projects deploy from GitHub.
• PHP runs only through your own Dockerfile.
• Every request passes through Cloudflare's network, which applies its own limits, such as a 100 MB request body.
• Prices are in Indian rupees, charged through Razorpay by UPI or card.
• Antideploy is a young platform run by a small team.

Moving a project from Railway to Antideploy

• A single web service deploys as it is. railway.json and railway.toml are noted but not applied; Antideploy works out the build and start commands from the code.
• A Postgres service is replaced by the database Antideploy creates, or kept: push its DATABASE_URL as a secret and your value wins.
• Workers, cron services, Redis, MySQL, MongoDB and volumes have no Antideploy equivalent. A project that depends on them is better left on Railway.
• Environment variables are pushed by the agent with PUT /api/v1/secrets.

The sentence to give your agent:

Deploy this project with Antideploy. Start by reading https://antideploy.com/llms.txt and follow it.

Frequently asked questions

Is Antideploy an alternative to Railway?

For a single web app with Postgres, yes: both run a long-running server, and Antideploy adds a free plan with fixed allowances, flat rupee pricing, and a platform that reads the code and creates the database by itself. For a project with several services, a worker, Redis, a disk, or an app that must never sleep, Railway is the better fit.

Do both run long-running servers?

Yes. Railway runs long-running containers, and so does Antideploy. The difference is that Antideploy apps sleep when idle on every plan, while Railway services stay awake unless serverless mode is turned on.

How do WebSockets compare?

Both keep them open. Railway says WebSocket connections are exempt from its request limits and can stay open indefinitely, even while idle. On Antideploy, an idle WebSocket stayed open for 330 seconds in our test, and Antideploy sets no time limit of its own on a connection.

Does Antideploy run on Railway?

The Antideploy platform does: its website, API and deploy workers run on Railway. The apps users deploy run on Fly.io machines in Singapore.

Do Antideploy apps sleep?

Yes, on every plan. An app with no traffic sleeps and wakes on the next request. In our measurements the first request after sleeping took 2.9 to 10 seconds for static sites and Python and Node.js servers, and 8.6 to 13.9 seconds for Next.js apps. Requests after that took 0.12 to 0.44 seconds for all but one app.

How does a coding agent log in to Antideploy?

With a device login. The agent requests a code, shows the user a link, and the user clicks Approve once in a browser where they are signed in. The agent then saves the token to ~/.antideploy/config.json and never needs the user to copy or paste a credential.

How we measured

WebSocket. On 19 September 2026 we opened one WebSocket, the same handshake a browser makes, to the Streamlit endpoint /_stcore/stream of an app running on Antideploy, sent nothing, and kept it open for 330 seconds. It stayed open for the whole time and closed when our client closed it (code 1000).

Waking from sleep. On 19 September 2026 we picked three sleeping apps at random for each stack, confirmed through Fly.io's API that each app's machine was stopped, and timed one request to the home page followed immediately by a second, from a connection in India. One of the three Vite apps did not answer within 60 seconds and is left out of the table. Times include the network round trip to Singapore.
