Stop guessing why your Railway deploy failed. Let your AI agent diagnose & fix it automatically in seconds.
This is a free, open-source skill built by a solo founder. If it saves you from one more deploy-crash-debug cycle, please:

Stop wasting hours debugging Railway deploys. This skill gives your AI agent the power to autonomously diagnose and fix Railway deployment crashes — OOM kills, healthcheck failures, database connection errors, and more. One command → agent collects logs, analyzes configs, matches patterns, and applies the fix.
Railway Deploy Skill is an OpenCode / Claude Code agent skill that supports FastAPI + Next.js + PostgreSQL stacks. All CLI commands verified against official railway --help.
| Feature | Manual Debugging | Railway Deploy Skill |
|---|---|---|
| ⏱ Time to fix | 30 min — 3 hours | 30 seconds |
| 🔍 Log analysis | You scroll through logs | Agent reads & matches patterns |
| 📚 Config checking | You check each file manually | Agent reads all files automatically |
| 🧠 Pattern recall | You remember past errors | 8 pre-built patterns |
| ✅ CLI accuracy | You might use wrong flags | Verified against railway --help |
| 🔓 Cost | Your billable time | Free, MIT licensed |
Railway's dashboard has a built-in AI agent for deployment diagnosis. Here's how they compare:
| Feature | Railway AI Agent (Dashboard) | Railway Deploy Skill (Ours) |
|---|---|---|
| 💰 Cost | Pay-per-token (Anthropic rates) | Free, unlimited |
| 🔑 API Key | Railway account required | Not needed |
| 📍 Where it works | Only in Railway dashboard | In your local AI agent (OpenCode, Claude Code, Cursor) |
| 🔌 Internet required | ✅ Yes (dashboard + cloud LLM) | Depends on your AI model (local = offline, cloud = online) |
| 🎯 Patterns covered | Generic LLM diagnosis | 8 specific Railway patterns |
| ⚡ Response time | Depends on LLM API | Instant — local CLI |
| 🔄 Auto-fix | Opens GitHub PR | Edits config files directly + sets env vars |
| 🧩 Customizable | ❌ No | ✅ Add your own patterns |
| 🔓 Vendor lock-in | Railway-only | Works with any AI agent, any cloud |
| 🚫 Usage limits | ✅ Hitting limits is common | ❌ No limits, use infinitely |
| 📜 License | Proprietary | MIT |
Bottom line: Railway's dashboard AI agent is great for quick diagnosis when you're already in the dashboard — but it's paid per-token, only works online, and can't be customized. This skill is free, works offline in your local AI agent, covers 8 specific Railway failure patterns, and you can add more. Use both — dashboard agent for quick checks, this skill for deep, automated fixes without leaving your editor or hitting token limits.
| Feature | Description |
|---|---|
| 🤖 Fully Autonomous | Agent collects logs, checks env vars, reads configs — no manual input |
| 🔍 8 Failure Patterns | From OOM kills to healthcheck timeouts |
| ⚡ One-Command Fix | Say "deploy crash" — agent handles the rest |
| 🛠 Stack-Specific | FastAPI, Next.js, PostgreSQL, Docker, Railpack |
| 📚 CLI-Accurate | All Railway CLI commands verified against official railway --help |
| 🔓 Open Source | MIT licensed. Free forever. Built by a solo founder. |
| # | Pattern | Error Signature | Fix |
|---|---|---|---|
| A | Build OOM | Killed, exit 137, Out of memory |
Reduce memory, output: "standalone" |
| B | No Start Command | No start command could be found |
Set in railway.json or settings |
| C | Port Binding | port already in use, service unavailable |
Use $PORT env var |
| D | Database Connection | ECONNREFUSED, timeout |
Check DATABASE_URL, reference vars |
| E | Healthcheck Failure | failed with service unavailable |
Add /health, allow healthcheck.railway.app |
| F | Python Dependencies | ModuleNotFoundError, pip fails |
Pin versions, add apt packages |
| G | Auto-Deploy Failure | Push triggers but deploy fails | Check railway.json, watch patterns |
| H | Monorepo Issues | Wrong service deploys | Set root directory, absolute paths |

Start a session with your AI agent and say:
"Railway deploy crash, diagnose using railway-deploy skill"
Or be more specific:
"Build failed with exit code 137 — check memory issue" "Auto-deploy error after git push" "FastAPI app deploy succeeds but healthcheck fails" "Database connection refused after deploy"

# Agent runs these automatically:

$ railway logs --build --lines 50
$ railway variable list --kv
$ railway status
# Agent reads project files:
# → package.json, railway.json, Dockerfile, next.config.ts
# Agent identifies pattern:
# → Pattern A: Build OOM (exit code 137)
# Agent applies fix:
# → Adds output: "standalone" to next.config.ts
# → railway variable set NODE_OPTIONS=--max-old-space-size=2048
# Agent verifies:
$ railway up
$ railway logs --lines 30
$ railway logs --build --lines 20| Technology | Status | Notes |
|---|---|---|
| Next.js | ✅ | Requires output: "standalone" |
| FastAPI | ✅ | Tested with uvicorn & hypercorn |
| PostgreSQL | ✅ | Railway plugin & external |
| Docker | ✅ | Multi-stage build, shell form env vars |
| Railpack | ✅ | Default Railway builder |
| Python 3.11+ | ✅ | pip, requirements.txt |
| TypeScript / JavaScript | ✅ | npm, yarn, pnpm, bun |
| Express / Nest.js | ✅ | Works with Node.js start commands |
| Django / Flask | ✅ | Works with Python start commands |
All commands verified against official railway --help output:
railway logs --lines 100 # View last 100 log lines
railway logs --build # Build logs only
