Railway deploys still paused? Here's a Railway alternative
Rotate your secrets first, then tell your coding agent "migrate us to Lizard": it redeploys your apps and workers, sets up Postgres, Redis and S3 and imports your data
lizard.build/unpause
> set fresh secrets on Lizard, don't copy the old ones
> apps, databases and agent sandboxes on one account, one bill
> first week free
The easy way to move is right here 👇
Deploys paused and secrets to rotate? Your agent can move you to Lizard sandboxes and hosting in one prompt
If your platform froze deploys this week, you don't have to wait it out. Rotate your secrets first, then hand the move to your coding agent
lizard.build/column
> install the Lizard Skill: npx skills add lizard-build/skill -g
> tell your agent "migrate us to Lizard": it redeploys your services and workers, provisions Postgres, Redis and S3 and imports your data
> set your new, rotated secrets on Lizard instead of copying the old ones
> point your domain and you're back to shipping
Works with Claude Code, Codex, Cursor and any agent with a terminal. Your agents can keep building in Lizard sandboxes, and the first week is free

An urgent notice from the Railway team

Migrate on Lizard easily via CLI
Builds are temporarily paused
We are currently investigating this issue
Status: Investigating status.railway.com/incident/…
We timed 1,200 sandbox boots. Lizard's median: 238 ms
300 cold starts each on Lizard, E2B, Daytona and Modal. Every ball in the video is one sandbox boot, dropped into a bin by how long it took to start
lizard.build/session
Median cold start:
> Lizard 238 ms
> E2B 270 ms
> Daytona 796 ms
> Modal 865 ms
Lizard had the lowest median and average of the four. When your agent spins up a sandbox for every task, that wait adds up fast. The full table, up to p99, is on our sandboxes page
Your agents sat idle all weekend. You paid for every hour of it
Most agent setups keep their machines running around the clock, even when nobody gives them work. 50 coding agents on Small sandboxes running 24/7 cost $136 a week. Paused outside working hours, the same 50 cost $36
lizard.build/replay
> a paused Lizard sandbox costs $0 an hour
> resume on Monday with the same memory, files and running processes
> billed per second while it runs, so a 10-minute task costs 10 minutes
> apps and databases on Lizard go to sleep on their own after 10 minutes with no requests
Pause your sandboxes when the work stops. Your agents won't notice, your bill will
