Automation and integrations decision
Zapier
A small, single-workspace automation tool is realistic for a capable engineer in ~30 hours, but Zapier's scale (9,000+ integrations) and long-running production infrastructure are durable advantages that make a full replacement impractical for an individual.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
Code Zapier publishes itself
Not a way out of the subscription — these are the vendor’s own repositories. Worth a look for how they build, and for anything you would have to integrate with.
What a replacement has to do
- Receive triggers (webhook/schedule) → map/transform data → call authenticated app actions (HTTP/API) → log/acknowledge and retry on failure
What it still won’t have
- Access to Zapier's 9,000+ pre-built app integrations
- Enterprise controls: SSO/SCIM, domain capture, advanced admin permissions
- Audit logs, log streaming, and built-in observability integrations
- SOC 2 / SOC 3 compliance and GDPR/CCPA features out of the box
- Managed connections, pre-built templates, and enterprise support/TA
What remains hard
- Integration maintenance
9,000+ app integrations
- Infrastructure at scale
13-year-old production infrastructure

Paying is—cheaper in year one.
On cash alone, building overtakes the subscription at 3 seats.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a self-hosted minimal automation platform in Node.js + Express, React UI, Postgres for storage, and Redis for queueing. In scope: webhook and scheduler triggers, credential storage with OAuth token refresh, a small visual editor (or JSON-based editor) to define trigger→action mappings with conditional logic, an execution worker that maps data to HTTP API calls with retries, and an audit/logging endpoint that streams to logs. Out of scope: building hundreds of pre-built app connectors (provide only a Postgres-stored HTTP connector template and OAuth connector template), enterprise SSO/SCIM, and SOC compliance. Include error handling, unit tests for core logic, and an integration test that demonstrates one webhook→third-party API action with retry and audit log entry.
How we checked
How the score was reached
- Partly verdict base52
- An open-source build was found+5
- 5 cited sources+3
- Price verified on pricing page+3
- Hard moats found in the evidence-3
- Evidence score60
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
