Choose Supabase if…
- ✓You want real SQL (Postgres)
- ✓Open-source / self-host matters
- ✓You''re building AI features (pgvector)
- ✓TypeScript-first dev experience
- ✓You hate vendor lock-in
Choose Firebase if…

Our recommendation
Pick Supabase if you want real SQL (Postgres), zero vendor lock-in, and a TypeScript-first developer experience. Pick Firebase if you're building mobile-first, need the most mature realtime database, or are deep in Google Cloud already. For new AI projects, Supabase's native pgvector support is a meaningful edge.
How to choose the right platform
Choosing between automation platforms isn't just about features — it's about matching the tool to your team's technical capability, budget constraints, and specific use cases. The "best" platform is the one your team will actually use consistently.
Decision framework
Ask these questions before committing to a platform:
- Who will build the automations? Non-technical users need visual builders (Zapier, Make). Developers prefer code-first tools (n8n, custom).
- How complex are your workflows? Simple A→B integrations work on any platform. Multi-step, branching workflows need Make or n8n.
- Do you need AI/LLM capabilities? Only n8n has native LangChain integration for AI agent workflows.
- What's your data sensitivity? If data must stay on your servers, only self-hosted options (n8n) qualify.
Migration considerations
Switching platforms after building 100+ workflows is painful. Factor in migration cost when choosing — it's worth paying slightly more upfront for the right platform than saving money now and facing a 6-month migration later.
