A Retool alternative for teams without developers
Retool is the tool for companies that already have developers: a visual component editor, with JavaScript and SQL, that connects to the databases and APIs you already run — even on your own servers. theo starts from the other side: you describe the internal tool you need, and it builds the app and the database for you, with no technical person in between.
Who each one is for
Retool assumes someone who assembles screens from components and writes the queries — productivity for people who already code. theo assumes the business owner, manager or analyst who knows what they need but doesn't want to build screens or write SQL.
Where Retool goes further
- Connects to what you already have: many databases and APIs, no data migration.
- Self-hosting on your own servers, as well as cloud.
- Enterprise controls: SSO, roles, audit logs and Git-based source control.
- Server-side workflows for automation.
For a company with an engineering team and IT requirements, it is a solid choice.
Where theo is simpler
- Describe instead of assemble: theo creates the screens, tables and queries from what you write.
- The database comes with it: each app gets its own tables in a managed PostgreSQL.
- Existing data: connect a company PostgreSQL or MySQL in read-only mode and build dashboards on top — see the PostgreSQL dashboard.
- Team roles and permissions, and ready-made templates to start from.
- No per-seat pricing.
Where theo does NOT replace Retool
If you must self-host, require corporate SSO or write back to the databases you already have, Retool fits and theo does not: theo runs on its own cloud, and external database connections are read-only by design.
Pricing
Retool charges per seat, with different prices for builders and end users, in US dollars; there is a free plan for a few users. theo starts free, with no credit card and no time limit. The platform's AI has a monthly message allowance; if you add your own AI key (Anthropic, OpenAI or Google) that allowance does not apply and you pay the provider directly. There is no paid plan today.

Frequently asked questions
- Is theo a Retool alternative?
- For internal tools at a company without a technical team, yes: you describe what you need and theo builds the app and the database. If you need self-hosting, corporate SSO or writing to existing databases, Retool is the better fit.
- Can theo connect to my existing database?
- It connects to PostgreSQL and MySQL in read-only mode, for dashboards and reports. It does not write to those databases.
- Do I need to know SQL?
- No. theo writes the queries from your description. If you know SQL, you can review the generated code.
- How much does theo cost?
- It starts free, with no credit card and no time limit, and no per-seat pricing. The platform's AI has a monthly message allowance; with your own AI key that allowance does not apply.
