Everruns Documentation

Everruns is a durable agentic harness engine built on Rust. It provides APIs for managing agents, sessions, and long-running tasks, with real-time SSE event streaming and PostgreSQL-backed durability.

Build directly inside a Rust application with the Everruns Framework, or use the Platform and SDK documentation for a durable deployment and remote clients.

What kind of help do you need?

The documentation is organised by what you’re trying to do.

FrameworkBuild and run agents in a Rust process with the application-facing everruns crate.
Learn — TutorialsHand-held lessons that take you from zero to a running agent. Start here if you're new.
Do — How-to guidesTask-oriented recipes for common problems. Use these when you know what you want to build.
Understand — ExplanationBackground and design rationale. Read these when reference docs aren't enough on their own.
Look up — ReferenceAPI endpoints, event types, capability catalog, CLI flags, environment variables. The dry stuff.
