REST + GraphQL APIs
Trigger workflows, read traces, manage artifacts and HITL tasks programmatically. Your CI/CD already knows how to talk to it.
Developers
Extend it. Govern it. Own the runtime.
You get APIs, SDKs and custom workers that compose with everything built in — without losing control, traceability or the right to leave.
Built for engineers
A real framework, not a closed black box.
Custom workers
Write your own worker in JavaScript, Python or shell. It shows up next to the built-in catalog like it always belonged there.
Webhooks & triggers
Webhook, cron, queue, manual, event and workflow triggers. Your stack decides the kickoff — we just listen for it.
Secret vault
Credentials live in a vault and resolve at runtime. Held in memory only as long as needed, with full audit on every retrieval.
Event traces
Causal traceability per worker. Reconstruct any run, replay any agent decision, export the chain for compliance.
Connector SDK
Build first-class integrations with the same surface as the built-ins. Your connector ships, others use it, you own the upstream.
Workflow as artifact
Versioned. Diffable. Replayable.
Workflows are first-class artifacts — graphs with explicit ports, policies and HITL gates. Source-controllable, diffable in PR review, deployable through your existing pipelines. The infra people on your team get to keep doing infra.
