You can drop Coolify, skip the 900 vibe-coded lines and still pay less than Railway
One dev ripped out 150,000 lines of PHP for 900 of his own. Coolify's creator replied that someone still has to maintain them
lizard.build/builds
Lizard does everything on his list, and you maintain none of it:
> push to GitHub, it redeploys
> builds on our servers, no local Docker
> managed Postgres and Redis next to the app
> your agent can deploy through the CLI
Usage-based and under Railway on every rate. One app on 1 vCPU and 2 GB, running all month:
> Lizard $36.52
> Railway $40.00
I think unfortunately @coolifyio is next on the chopping block 💀
I don't need 150,000 lines of PHP and 272 dashboard screens anymore, I just need a GitHub webhook, docker build, and an MCP tool for my agent
I would privately open-source this by invite only

What people don't realize about the $6.3B Binance hack
It started on one DevOps engineer's laptop. Hours later, a fake Claude Code extension hit up to 5,000 Cursor users
lizard.build/security
Lizard runs untrusted code in a throwaway microVM, far away from your keys:
> boots in 228 ms
> 10 minutes on Lizard: $0.0027
> same box on Modal: $0.0397
$6.3 billion vs $0.0027. Your call
What people don't realize: a separate sandbox doesn't mean a separate CPU
OpenAI's agents had no internet, no network and no shared files. They still found a way to signal each other through the hardware underneath
How isolation actually stacks up:
> container: shared kernel, the easiest wall to climb
> microVM: its own kernel, that's every Lizard sandbox
> dedicated node: no neighbors on your CPU
lizard.build/isolation
Most agent workloads are fine on the middle layer. If yours are the kind that go looking for side channels, Lizard Enterprise runs them on dedicated nodes.
Lizard vs InstaBox (@insforge), $10,000 each. Closest race we've run so far
Same small sandbox on both, 2 vCPU / 4 GB with 5 GB disk:
> Lizard $0.0162/h, disk included: 617,284 h
> InstaBox $0.017/h + $0.00055/h disk: 569,801 h
lizard.build/box
InstaBox costs 8% more per hour. On a $10k budget that's 47,483 sandbox hours you don't get, enough to run 16 agents 8 hours a day for a whole year
Both bill per second and both run real VMs with their own kernel, so price is where they split. Pause a Lizard sandbox and compute stops billing
100x machines.
At 10,000 sandboxes @modal $532,224 more every month

Enterprise has no cap on how many run at once.

Some users asked where is comparison with @boatdotdev. Added it, and scaled the bill to a real agent fleet
100 small sandboxes, 8 hours a day, 30 days:

Very close, but Lizard still better price!

This list is missing the sandbox that costs $11.66 a month. Modal charges $171 for the same box
Same small sandbox, running 24/7 for 30 days:

Most goated alternatives to Vercel sandbox:
1. E2B (@e2b) - e2b.dev
2. Instabox (@insforge) - instabox.sh
3. Modal sandbox(@modal ) - modal.com
4. Sandboxer(by @jonoringer) - sandboxer.com
5. Daytona(@daytonaio ) - daytona.io
6. Cloudflare Sandbox(@Cloudflare ) - cloudflare.com/products/sand…
There is. It's metal.
Software get copied in a week. Hardware, power and servers you own don't.
Get a nice long term spot in sandbox industry:
