Curated, verified, and actually free. No trials, no crippled tiers. Star counts and last-activity dates checked by hand, not scraped and forgotten.
ZombieZapier with a Docker bill and no task meter.
licenseMIT
runsyour machine or their cloud
installHosted signup, single-container Docker for testing, or Docker Compose for production
enginesAI pieces connect to providers including OpenAI, Anthropic and Google Gemini
dataFlows and credentials in PostgreSQL; queues and cache in Redis; files use configured persistent or object storage
vs ZapierIts connector catalog, edge-case handling, documentation and vendor support are smaller than Zapier's, and self-hosted OAuth connections can be fiddly.
setupSelf-hosting needs Docker, PostgreSQL, Redis, a public URL and OAuth credentials for many connectors

licenseAGPL-3.0
runsyour server
installDocker Compose
dataAutomation definitions and credentials in PostgreSQL; jobs and cache in Redis on the user's server

The standard self-hosted answer: broad, durable, and fair-code rather than open source.
licensen8n Sustainable Use
runsyour machine or their cloud
installHosted signup, npx or Docker
enginesOpenAI, Anthropic, Google and many hosted or open-model providers through AI nodes and LangChain integrations
dataSelf-hosting defaults to SQLite in the persistent .n8n directory; PostgreSQL is supported, credentials are encrypted in the database, and binary files use filesystem or object storage
vs ZapierIt is more technical to build and debug, and self-hosting moves reliability and upgrades onto you while Zapier offers a larger turnkey app ecosystem.
setupSelf-hosting needs persistent storage, a public webhook URL, credentials and operations; the Sustainable Use License is source-available rather than OSI open source

They pay because every new app connection is already packaged and maintained. If none of that applies to you, any pick above saves $359.88 a year.
Is there a free alternative to Zapier?
Yes: Activepieces Community Edition, Automatisch, n8n Community Edition. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own Zapier?
Our verdict is KINDA. A few personal automations are easy; Zapier's moat is the 9,000+ app integration catalog, auth handling, retries, task history, UI, and reliability. If you'd rather build, the exact one-shot prompt is free at canivibecodeit.com/zapier.
