Runloop review

Runloop ranks seventh and is the most specialized product here. It sells devboxes for AI coding agents that run in micro-VMs with a container layer inside, which the vendor describes as two layers of security, plus arm64 and x86 support and command execution in about 100ms. Blueprints and snapshots make environments repeatable, repo connections pull in code, agents can control browsers and computers, and MCP servers and SSH tunnels connect outside tools. Its evaluation and benchmark tools are the main reason to choose it over a general sandbox. The Basic plan has no subscription fee and bills devbox CPU at $0.108 per CPU hour and memory at $0.0252 per GB hour; Pro adds suspend and resume, 1 TB of free storage and Slack support for $250 a month. New accounts get $50 of credit with Pro features. The vendor's own example puts a 2 CPU, 4 GB devbox at about $60 of compute a month at 8 hours a day.

Who it is for

Teams building AI software engineering agents who also want benchmarks and evaluations next to their sandboxes.
