n8nn8n
Source-available automation with real agent nodes
n8n started as a self-hostable Zapier alternative and has become the default choice for teams who want automation and agents in the same canvas without per-task billing. Its execution-based pricing is the single biggest reason teams migrate to it.
[ 01 ] The verdict
The best value in automation by a wide margin, provided someone on the team is comfortable running infrastructure. Per-execution billing makes deep multi-step workflows economically viable in a way per-task competitors cannot match.
Best for
Technical teams running high-volume, multi-step workflows who want cost control and the option to self-host.
Watch out
Self-hosting means you own upgrades, queue mode and backups. The 'free' tier has a real operational cost attached.
Strengths
- Execution-based billing is far cheaper than per-task at depth
- Self-hostable, satisfying strict data-residency needs
- Native agent and LLM nodes alongside classic connectors
- Arbitrary JavaScript and Python in any node
Trade-offs
- Steeper learning curve than consumer automation tools
- Connector depth trails the largest incumbents
- Self-hosted operations require genuine ownership
[ 02 ] What it actually does
What n8n actually ships.
Visual workflow canvas
Node-based editor with branching, looping, error paths and sub-workflows.
AI agent nodes
Tool-calling agents that sit inside a workflow and hand results back to deterministic steps.
Code nodes
Drop into JavaScript or Python whenever the visual abstraction gets in the way.
Queue mode
Horizontal scaling with worker processes for high-throughput production use.
