n8n
Pros
- + Unlimited steps per execution: my 20-node nightly sync counted as one execution, so complexity stops driving cost (n8n.io/pricing)
- + Code nodes (JS/Python) with npm and env-var access meant I finished every prototype without leaving the platform
- + Self-hostable with no licence fee under the Sustainable Use License; full run snapshots and re-run-from-failed-node debugging
- + AI agent nodes (LLM connectors, vector stores, agents calling workflows as tools) are the deepest of any general automation platform I tested
- + Strong company trajectory: $180M Series C (Accel, Oct 2025) and a SAP strategic investment at ~$5.2B in May 2026
Cons
- - Not open source — the Sustainable Use License (fair-code) forbids offering n8n as a hosted service and fails OSI procurement checks
- - Assumes engineering literacy: JSON paths, expressions, and async data structures stumped every ops-only user I watched try it
- - Self-hosting carries real ops cost — queue mode, worker scaling and upgrades took me hours that a managed platform absorbs
- - Documentation is thin at the edges; AI node options and queue-mode config sent me to community forum threads
- - Business cloud tier is self-hosted-only at time of writing (cloud waitlisted), leaving a gap between Pro's 10K executions and Enterprise
Windmill
Pros
- + Script-first model: typed functions become endpoints, jobs and flow steps with auto-generated UIs — my nightly pipeline was rebuilt in one Docker session
- + Free self-hosted tier carries unlimited executions, not a trial disguised as a plan
- + Rust execution engine kept orchestration overhead sub-second between flow steps in my tests
- + Worker-group model scales throughput with replicas and tag routing instead of redesigns
- + Transparent per-unit Enterprise pricing ($20/builder, $10/non-builder, $50/worker) with published SLA terms
Cons
- - Zero no-code path — teams without developers cannot use it at any price
- - Prebuilt Community Edition images bundle proprietary Windmill Labs terms (no resale/wrapping/modifying), separate from the AGPLv3 source build
- - Worker groups and role configuration have a real learning curve before the platform pays off
- - Small vendor (under twenty employees in 2024 reporting, ~$15M raised) relative to the incumbents it replaces
- - Flow durability is lighter than Temporal for mission-critical long-running orchestration
