Get started
Actae is a durable execution substrate: an ordered event log, versioned state, exact-boundary forking, and coordination primitives behind one endpoint, with SDKs in Python, Go, and TypeScript. The pages below take you from a running server to production workflows.
Quickstart
Run Actae locally or in the Cloud, install an SDK, record and replay your first events in minutes.
ReadCore concepts
Channels, events, cursors, replay-to-live, atomic state transitions, and idempotency guarantees.
ReadForking & recovery
Exact-boundary forks with immutable receipts, crash recovery, resume, and fidelity evidence.
ReadCoordination
Idempotent tool executions, durable consumer groups, persisted wake-ups, and fan-out delivery.
ReadExperiments
Experiment groups, outcomes, ranking, promotion, structural diffs, and decision trails.
ReadSessions & adapters
AgentSession step/fork/resume lifecycle plus adapters for LangGraph, LangChain, Claude, OpenAI, CrewAI, and Copilot.
ReadPython SDK
actae-client — async-first, sync bridge, WebSocket streaming, AgentSession, and adapters.
ReadGo SDK
go get actae — int64-faithful payloads, transactional state store, Copilot SDK integration.
ReadTypeScript SDK
@actae/sdk — ESM-only, bigint-safe JSON, subpath adapter exports, and live streaming.
ReadLLM documentation pack
Copy-paste markdown dumps of the full documentation, ready to drop into any LLM chat.
ReadPaste Actae into your LLM
Every documentation page is available as a raw markdown dump — the exact format LLMs consume best. One click copies a page, or grab the entire pack as a single file and drop it in your chat to give the model complete, current knowledge of Actae.
