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 10,000 small sandboxes, 8 hours a day, 30 days: > Lizard $38,880 > Boat $43,200 > @Cloudflare $167,184 > Vercel $264,960 > @e2b $397,440 > Daytona $397,440 > Modal $571,104 lizard.build/now 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: > Lizard $389 > Boat $432 > Cloudflare $1,673 > Vercel $2,650 > E2B $3,974 > Daytona $3,974 > Modal $5,712 lizard.build/boat Very close, but Lizard still better price!

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: lizard.build/moat
there is no moat

700 VMs of minecraft is cool. we brought the shotgun: 50 Lizard sandboxes running doom One sandbox first: 4 vCPU, 8 GB, a desktop, Doom installed. It was up in under a second. We snapshotted it in 18 seconds, then restored that snapshot 50 times lizard.build/launch Every copy loaded its own map and its own bot, with a real screen recording from each desktop. No mockups, the grid in the video is all 50 > 50 sandboxes, 4 vCPU / 8 GB each > one snapshot, 50 different games > $0.0324/h per sandbox, $1.62/h for the whole grid > desktop, snapshots, pause and resume built in Next time we'll let the agents play
nice try we spun up 700 boat.dev VMs 4c x 8gb, started codex + minecraft, made it all play in multiplayer together they all booted from a snapshot in the first 10s, which cost $0.07, same price per VM, core & ram but much more impressive capabilities and scale

Railway's report is out: rotate every secret stored before Oct 21! If you're rotating everything anyway, set the new keys on Lizard and let your coding agent move the rest. Apps, workers, Postgres, Redis, S3 and your agent sandboxes, on one bill lizard.build/rotate > npx skills add lizard-build/skill -g > tell your agent "migrate us to Lizard" > it recreates services, databases and the data inside Agent sandboxes come out 18x cheaper: 10 running 24/7 cost $118/mo on Lizard vs ~$2,129 on Railway.
