Durability beside your agent—not inside its brain.
Actae is an execution substrate available as managed Cloud or self-hosted infrastructure. Your application remains authoritative; Actae persists the boundaries that make recovery, safe retry, and branching possible.
Your application
Owns prompts, models, tools, planning, and the execution loop.
Actae SDK
Marks durable steps, state transitions, tool claims, forks, and subscriptions.
Actae server
Assigns ordered cursors, enforces optimistic boundaries, coordinates leases, and records lineage.
PostgreSQL data boundary
Self-host in your environment or use the dedicated persistent data store attached to an Actae Cloud runtime.
Facts commit together.
Atomic transitions persist the event and resulting state in one transaction. Expected-version and expected-cursor guards reject stale writers instead of silently overwriting progress.
Replay → liveCatch up to a cursor, synchronize, then receive live delivery without an application-built handoff.
Exact-boundary forksEach child gets inherited state and an immutable receipt describing the requested and resolved boundary.
Tool execution ledgerStable operation keys, parameter fingerprints, leases, fencing tokens, and stored results make ambiguous retries explicit.
