STACKSYNC WORKFLOW AUTOMATION

Everything serious workflow automation needs.

Human approvals, governance, secrets, and a connector kit for anything you can't find off the shelf — the controls that make automation safe to run in production.

HUMAN IN THE LOOP

Pause for a human
exactly when it matters.

Insert approval steps anywhere in a workflow. The run pauses with the full payload, waits for a decision — approve, reject, or edit — then continues. No lost state, no timeouts, no shadow spreadsheets.

See approvals in action

01 Drop approval gates into any workflow without writing glue code
02 Runs pause safely with full context and wait for a human decision
03 Every approval is logged, attributable, and replayable end to end

Runs pause safely with full context until a human decides — no timeouts.

SECURITY & GOVERNANCE

Feature controls, audit logs,
and governance built in.

Role-based access controls decide who can build, run, and deploy. Every deploy, run, secret access, and approval is captured in an immutable audit log your compliance team can sign off on.

Explore governance

01 Granular RBAC across workflows, runs, secrets, and approvals
02 Immutable, attributable audit log of every action and deploy
03 SOC 2 Type II, ISO 27001, HIPAA — governance you can prove

VARIABLES & SECRETS

Secrets and variables,
managed the right way.

Store API keys, tokens, and environment variables in an encrypted vault and reference them anywhere with a single expression. Values are injected at runtime, scoped per environment, and never hard-coded or written to a log.

Manage secrets

01 AES-256 encrypted at rest, injected only at runtime
02 Scope values per environment — prod, staging, and dev stay separate
03 Reference any secret with {{ secrets.NAME }} — never paste a key again

CONNECTOR DEVELOPMENT KIT

Describe the API.
AI builds the connector.

Don't have a connector? Describe the API in plain English and the Connector Development Kit scaffolds it for you — auth, endpoints, schema, and tests — so you can sync any system on your stack in under a minute.

Build a connector

01 AI generates auth, endpoints, and schemas from a plain-English brief
02 Full code access — extend, version, and test like any other connector
03 Ship a private connector for any internal or long-tail API
