Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
n8n
- Source-available (Sustainable Use License), not true OSI open source; some enterprise features (SSO, log streaming, external secrets) are gated behind paid tiers.
- Self-hosted instances require you to manage your own queue/Redis and Postgres for scaling and reliability.
- Far fewer pre-built app connectors than Zapier's 6,000+ catalog.
- Concurrency and execution throughput on the free self-hosted tier require manual queue-mode tuning.
StackStorm
- Complex multi-component architecture (RabbitMQ, MongoDB, multiple services); steep to install and operate.
- Ops-focused rather than a business-friendly no-code iPaaS; not aimed at marketing/sales automations.
- Workflow authoring uses YAML/Orquesta, which is more technical than visual builders.
- Smaller community and slower momentum than n8n or modern alternatives.
Bottom line
Choose n8n if you want the lower-effort setup; choose n8n for the larger community and ecosystem. n8n has seen more recent development. Open each guide below for deploy steps and the full feature gap.
