n8n alternatives (2026)
n8n: The workflow engine with a catch in the LICENSE.md. SUL, not OSI.
Its Catch: Sustainable Use License is not OSI.
Below: 8 free or free-tier tools from the same category (CI/CD tools), free and open source first, then the closest match by shared tags. Each keeps its own Catch.
Free / OSS · OSS/MIT · 222 GitHub stars
VerdictSelf-hosted GitHub Actions with real VM isolation — promising, but young; try it beside your existing CI first.
CatchYou run a server, not a one-shot CLI — expose it on a tailnet, tunnel or your own domain and keep it patched. It is a small, young project (first commit mid-2026), so expect rough edges and pin versions. Vs act (runs workflows locally in Docker containers with one command): preloop is the heavier choice when you want real isolation and a standing CI service you own.
Free / OSS · Apache-2.0 · 16.4k GitHub stars
VerdictApache-2.0 portable CI. The pipeline is code; Cloud is optional; its pricing is not confirmed here.
CatchYou need Docker or a compatible engine. Rewriting mature CI YAML is a project, not an afternoon. Dagger Cloud is a separate product with its own pricing.
Free / OSS · Apache-2.0 · 8k GitHub stars
VerdictApache-2.0 container CI. Self-host free forever; no SaaS tier.
CatchSelf-host only — not GitHub Actions managed UX. Smaller plugin ecosystem than Actions/Drone-era commercial. You own runners, secrets, and forge OAuth. Distinct from GitHub Actions and Buildkite hosted.
Free / OSS · Apache-2.0 · 12.3k GitHub stars
VerdictApache-2.0 changelog CLI. Free forever; turn conventional history into release notes.
CatchVs changesets / release-please (monorepo version+PR bots) and hand-edited CHANGELOG.md: git-cliff is a *generator from history*, not a publish orchestrator. Garbage commits in, garbage sections out — you still need commit discipline and a template you trust.
Free / OSS · OSS/MIT · 72.4k GitHub stars
VerdictMIT local Actions runner. Free forever; debug the workflow before you burn a push.
CatchVs hosted GitHub Actions and Woodpecker (self-host container CI): act is a *local emulator*, not a forge runner fleet and not a replacement for GitHub-hosted minutes. Event payload fidelity is incomplete; secrets, service containers, and some actions still surprise. Needs a Docker engine.
Free / OSS · OSS/MIT · 12.5k GitHub stars
VerdictMIT monorepo versioning. Free forever; write the change, let the bot bump the graph.
CatchVs git-cliff (changelog *from commit history*) and release-please: Changesets is *intent-first* (you write the change note), not history-parser-first. Empty or late changesets mean silent version drift. It versions packages — it does not replace your publish secrets or npm 2FA.
Free / OSS · OSS/MIT · 15.3k GitHub stars
VerdictAn underrated all-in-one GitLab alternative — strong if you want CI and code intelligence in one box.
CatchIt is one big Java application, heavier than Gitea or Gogs. Starting with 16.9.0, Intel Macs and FreeBSD are no longer supported. Issues and PRs live on the project's own instance (code.onedev.io), not GitHub, so the GitHub repo is a mirror. Fewer third-party integrations than GitLab.
Free tier · Freemium
VerdictThe default CI/CD for GitHub repositories.
CatchYAML syntax has a learning curve. Debugging failed workflows is frustrating. Costs scale with build minutes. Complex workflows become hard to maintain.
