AI workflowsthat actually ship.

One runtime. Every tool. Multi-step agent work that doesn't fall over on the third call.

What it does

Most automation breaks when the work gets messy. FlowSync's runtime handles branching, retries, human approvals, and live data — the same way a senior engineer would.

Capabilities

Built for the work AI can actually finish.

01 / 06

Multi-step agent runtime

Long-running agents that plan, branch, retry, and ask for approval — without falling over on the third tool call.

02 / 06

Universal connectors

Pre-built adapters for GitHub, Linear, Notion, Slack, Stripe, Postgres, plus a 30-second SDK for your internal APIs.

03 / 06

Workflow studio

Drag, drop, branch, version. Edit in the UI or commit YAML — your call. Production runs are auditable line-by-line.

04 / 06

Live observability

See every prompt, tool call, retry, and decision in real time. Trace costs, latency, and outcomes per workflow.

05 / 06

Approvals & guardrails

Pause for human approval on risky steps. Hard-block writes outside policy. Test in shadow before promoting.

06 / 06

Self-improving evals

Capture every production run as an eval. Compare model versions, prompts, and tool choices against the real workload.

Built like an engineer

A runtime, not a chatbot.

Most agent frameworks treat every run like a fresh conversation. FlowSync treats them like jobs — durable state, idempotent steps, deterministic replay, version-controlled prompts. The kind of primitives you'd want before pointing AI at anything that matters.

Durable state per workflow
Steps survive restarts, timeouts, and partial failures.
Idempotent tool calls
Same input, same output. Replay any run safely.
Versioned prompts + adapters
Promote, roll back, A/B test — git-tracked.
How it works

Three steps. Live in a week.

01

Connect

Authenticate the tools your team already lives in. Five minutes, OAuth, no proxies.

02

Compose

Describe the workflow in natural language or YAML. FlowSync wires the steps and proposes the data shape.

03

Run

Trigger from a webhook, schedule, or chat. Watch the trace render in real time. Roll back any step.

The shift

Stop writing glue code. Compose workflows.
