Open-source AI infrastructure

Agents as code. A runtime that's yours.

Define agents as code and run them with persistent sessions, isolated sandboxes, tools, approvals, and observability on Everstack.

Agents as code

Keep instructions, runtime policy, skills, tools, subagents, and schedules beside the code they operate, then review every behavior change through version control.

Persistent sessions on infrastructure you own

Everstack manages sessions, sandbox isolation, memory, approvals, streaming, subagent coordination, limits, and OpenTelemetry-native traces. After a server restart, interrupted turns must be reissued from the last checkpoint; they do not automatically replay.
