Only one of these four is actually a Zapier replacement. The other three solve adjacent problems people mistake for it.
This is the list where the star counts are most misleading, so let me say it plainly: of the four projects below, only n8n is genuinely a Zapier replacement. The other three are excellent tools that get filed under “Zapier alternative” because they also “do automation” — but Huginn, Airflow, and Activepieces solve adjacent problems, and picking one of them expecting Zapier will lead to weeks of fighting the wrong tool.
n8n — the actual answer
n8n (188.9k stars — the most of any project anywhere on this site, by a wide
margin) is the self-hosted Zapier. Visual workflow builder, 400+ integrations,
trigger-action Zaps with the crucial addition that you can drop into
JavaScript expressions when the no-code path runs out. The headline win is
economic: Zapier charges per task, and a busy automation can get expensive
fast; self-hosted n8n removes the per-task meter entirely. The license is the
one nuance to understand — the card shows NOASSERTION because n8n uses a
“fair-code” Sustainable Use License, not a classic open-source license.
For internal company automations this is fine; you may not, however, host n8n
as a competing automation service you sell. Read the license before you
build a product on it; for replacing your own Zaps, it is exactly right.
Huginn — for monitoring and scraping, not API-to-API glue
Huginn (49.3k stars, Ruby, MIT) is a wonderful tool aimed at a different target: agents that watch things (a web page, a feed, a price) and act when they change. If your Zapier usage was “ping me when this website updates” or “scrape this and email me,” Huginn is arguably better than Zapier was. If your Zapier usage was “when a Typeform comes in, create a row and post to Slack,” Huginn’s configuration model is far more involved than n8n’s visual editor for that, and you will be happier with n8n. MIT-licensed, the cleanest terms here.
Airflow — a data-pipeline orchestrator wearing the wrong label
Airflow (45.5k stars, Python, Apache-2.0) is industrial-grade, but it is built for scheduled batch data pipelines — DAGs that run nightly ETL, not webhook-triggered “when X happens, do Y” automations. It is a poor direct substitute for event-driven Zapier workflows, and using it as one means bending a batch scheduler into a real-time shape it resists. Apache-2.0 and genuinely best-in-class — for the job it is actually for, which is not this one. If your “Zaps” were really nightly data jobs, Airflow is the right tool and Zapier was the wrong one all along.
Activepieces — the legitimate runner-up to n8n
Activepieces (22.3k stars, TypeScript, NOASSERTION) is the one other project
here that is aiming at the Zapier niche — visual no-code automation, with a
strong recent lean into AI agents and MCP. It is a reasonable n8n alternative,
particularly if its AI-workflow direction matches where you are headed. The
honest reason to default to n8n instead is ecosystem maturity: n8n’s far
larger community means more pre-built integrations and more answers when a
workflow breaks at 2am. Its card license is also NOASSERTION (fair-code
style), so the same “fine for internal use, read it before reselling” caveat
applies.
The bottom line
Replacing Zapier’s event-driven, multi-app glue: n8n, with Activepieces as the runner-up. Replacing “watch the web and alert me”: Huginn. Replacing scheduled data pipelines: Airflow — but that was never really Zapier. Match the tool to which of those you were actually doing.
Comparison notes
n8n self-hosted provides a visual workflow builder with JavaScript expression support and over 400 integrations, covering most Zapier use cases at no per-task cost but adding server maintenance overhead and a steeper initial setup than Zapier's fully managed service. Huginn is a Ruby-based agent automation system more aligned with web scraping and monitoring than API-to-API integrations, and has a significantly steeper configuration curve than n8n's visual editor. Apache Airflow is designed for batch data pipeline orchestration rather than real-time webhook-driven automation, making it a poor direct replacement for most Zapier event-triggered workflows.
Migration tips
- Audit your active Zaps and verify which triggers and actions n8n's integration library covers before committing to migration — most major SaaS webhooks are supported but niche integrations may require custom HTTP nodes.
- Self-host n8n using Docker with a PostgreSQL backend to support workflow execution history and production reliability beyond the default SQLite configuration limit.
- Test each migrated workflow manually and run parallel execution with Zapier for one week before disabling original Zaps to catch edge cases.
Which alternative should you pick?
We don't believe in a single "best" answer here — the right project depends on your license constraints, team size, and tolerance for early-stage tooling. The 4 projects above each have a distinct profile. Use this decision tree:
- You want the most active community and the lowest risk of abandonment → n8n. 193,385★ — the largest user base in this list, which usually means more StackOverflow answers, more plugins, and more deployment runbooks online.
- You ship commercial software and need to ship modified code without releasing source → huginn. MIT licensed — modify and embed without copyleft obligations.
License & commercial-use notes
For an open-source replacement the license often matters more than any single feature — it decides whether you can modify the project, embed it in a product, or offer it as a hosted service. Here is how the 4 projects on this page break down:
- Permissive (huginn, airflow) — MIT / Apache / BSD / ISC — modify and embed inside a commercial product with no copyleft obligation. The safest bucket for shipping in a proprietary codebase.
- Unverified license (n8n, activepieces) — GitHub returned no clear SPDX id. Treat as all-rights-reserved until you read the project's LICENSE file directly — do not assume commercial use is permitted.
License fields come from the GitHub API's SPDX classification and can lag a relicense. The repository linked on each card is authoritative — confirm its LICENSE file before any license-sensitive deployment.

Frequently asked questions
How do these 4 alternatives compare on maintenance health?
4 of 4 have shipped a commit in the last 12 months. At least one project here has 5,000+ GitHub stars, which usually correlates with sustained maintainership. Always check the last-pushed date in the cards above and read the latest 5 closed issues — those two signals together catch 80% of abandoned-project cases.
