How Retool compares
| Retool | Baserow + Appsmith | |
|---|---|---|
| Pricing model | Per-user (builder vs internal) | Open-source or fair-code license; you pay the host |
| Hosting | Vendor cloud | Self-hosted on Railway or any VPS |
| Rough monthly cost | Team builder $10/mo billed annually ($12 monthly) source | Hosting only — no SaaS seat meter in this repo |
FAQ
- Is it free?
- The Baserow + Appsmith licenses are open source or fair-code. You still pay hosting (Railway or any VPS) and any APIs the stack calls. There is no Retool seat or task bill on this path.
- Can I migrate from Retool?
- Yes. Start with the workflows or data you actually use, then cut over. The Baserow + Appsmith stack page has the agent prompt and the cost table; most teams rebuild the slice that matters and leave old Retool links until they expire.
- How do I deploy it?
- Open the Baserow + Appsmith stack, copy the agent prompt, and deploy on Railway (one service, PORT, and a volume when the app needs disk). Placeholder: Baserow + Appsmith + Postgres. Medium complexity; second-wave template.
- What does this replace?
- Airtable / Retool. The published small-team estimate on this stack is $2,400 a year.
