Open-source alternatives guide · Updated 2026
Compare the best free and open-source alternatives to n8n — 7 verified projects with explicit catalog relationships. Inspect licenses, GitHub activity, self-hosting signals, and migration fit before you switch.
Only explicit alternative relationships are shown—never inferred competitor claims.
This guide compares 7 verified open-source alternatives to n8n, including Flowise, Kestra, ActivePieces, and Automa.
Projects appear across AI & Machine Learning, Content & Collaboration, and Data & Analytics. 2 options include a self-hosting signal — see the self-hosted catalog. Ranking follows public GitHub stars and recorded momentum—not vendor marketing. Compare projects side by side, then confirm license fit, migration effort, and operational ownership before adopting any option.
Teams replacing Zapier/Make—or comparing automation platforms adjacent to n8n—while deciding between self-host and managed.
Migration tip: Inventory triggers, credentials, and error handling first. Rebuild one production workflow end-to-end before migrating the rest of the automation estate.
Strongest repository-activity signal: Flowise · Jump to ranking · 54.7K stars
n8n is a workflow automation platform with visual nodes, code steps, and AI agent hooks. People search for alternatives when they want a different license model, simpler ops, or a closer fit to Zapier/Make-style SaaS without n8n’s specific runtime.
Compare capabilities, licensing, and ownership model. Stars help with discovery; they are not a security or product-fit guarantee.

Map must-have capabilitiesList the workflows in n8n you cannot drop during migration.
Verify the licenseConfirm it fits your use, distribution, and compliance model. Browse license briefs.
Run a proof of conceptTest real data, integrations, clients, and failure modes. Use Compare for side-by-side checks.
Plan ownershipAssess upgrades, backups, support, and an exit path. Read when self-hosting is worth it.
n8n publishes source under a fair-code style license with commercial terms for some uses. Always verify the current LICENSE and whether your deployment needs a commercial agreement.
Activepieces, Windmill, Temporal-based stacks, and Huginn-style tools cover overlapping automation jobs. Choose based on visual builders versus code-first workflows and ops complexity.
Self-hosting helps with data residency and credential control, but you own upgrades, queue reliability, and secret rotation. Start with non-critical workflows.
Narrow the same alternatives by search, license, tags, or self-hosting signals when you need a tighter shortlist.
