Structa
AI database schema generator that turns plain English into validated SQL, Prisma schemas, and ER diagrams.
Structa is worth a look if your problem is schema design accuracy, not SQL autocomplete. The visual editor plus validation is the part ChatGPT can't replicate, and the $19/mo Pro or $299 lifetime tier is cheap for anyone shipping multiple projects a year. It fits full-stack developers and indie hackers who are tired of fixing hallucinated foreign keys by hand. It stops being a fit the moment you need a hosted database — Structa designs schemas, it doesn't run them — or a replacement ORM, since Prisma remains your runtime layer. If you just need a schema once, the free 3-schema allowance may be enough end to end.

Skip Structa if you need a hosted or managed database rather than a design-and-export layer, or if you need Structa to replace Prisma as your runtime ORM instead of generating schemas upstream of it.
Unlimited SQL exports sit behind a paid plan — the free tier only includes 1 export total, so the second schema you actually ship triggers an upgrade.
Structa's pricing spreads across the whole range: free for 3 schemas, $4.99/week for a burst of project work, $19/mo Pro for multiple projects a month, $299 one-time for lifetime ownership, and $25/seat/month for teams. It sits well below enterprise data-modeling suites and only slightly above a raw ChatGPT subscription you'd otherwise be repairing by hand. Solo developers who shipped one project will find Pro unnecessary; anyone shipping several a year will find the $19/mo tier cheap against

About Structa
Structa is an AI database schema generator that converts a plain-English description of your app into a working database design — validated SQL, Prisma schemas, migration files, and shareable ER diagrams. Instead of pasting into a chat window and hand-fixing hallucinated constraints, you get the design on a visual canvas: drag, drop, and connect tables like blocks, then edit fields and relationships directly. The AI handles constraints, indexes, and foreign keys, validation warnings flag broken relationships before you export, and AI Fix repairs schema errors without a full regeneration. Exports cover SQL for any database, Prisma schemas, and migration files, with one-click deployment to Supabase that applies smart migrations. The free entry point gives you 3 schemas total and 1 export with no credit card and no account. Paid tiers raise saved-schema ceilings to 50 (Weekly) or 200 (Pro, Lifetime), unlock premium AI models, AI Fix, and full validation. Team workspaces at $25/seat/month add shared workspaces, role management, and centralized owner billing. Structa launched in December 2026 as an AI database designer for developers, currently showing 4.8/5 from 13 reviews and 1K+ schemas created. Compared to ChatGPT or a raw LLM prompt, Structa trades prompt-and-paste for a validated visual workflow; against Prisma's own tooling, it stays an upstream design layer rather than a replacement ORM.
Behind the Verdict
The core bet Structa makes is that the hard part of AI database design is not the generation, it's the correctness and the ability to revise. The marketing pages lean hard on this: ChatGPT produces 'copy-paste SQL with formatting issues' and 'hallucinated constraints and relationships' with no visual preview and no path to iterate except re-prompting. Structa's answer is a visual ER diagram editor where you drag, drop, and connect tables, a validation layer that surfaces broken relationships and missing constraints before export, and an AI Fix action that repairs errors without regenerating the whole schema. That's a real workflow difference, not a cosmetic one, because a schema bug like a missing foreign key or an unindexed join column is exactly the kind of thing you discover after the database is live. The exports are the practical proof of usefulness. You get SQL for any database, Prisma schemas, and migration files, with shareable ER diagram links, and one-click deployment to Supabase with smart migrations on paid tiers. Supabase users get the shortest path here, which is also the clearest limitation: the documented integration footprint is Supabase, and Structa is explicitly a design layer rather than a hosted database or a Prisma replacement. If your team expects a managed backend or a documented API surface, this isn't that. The pricing shape is unusually flexible for this category. A free entry with 3 schemas and 1 export and no account, a $4.99/week tier for someone mid-project who needs 100 schemas that week, $19/mo Pro with unlimited AI schemas, 200 saved schemas, AI Fix and full validation, a $299 one-time Lifetime with lifetime updates and premium support, and a $25/seat/month Team plan with shared workspace, role management and centralized owner billing. The Weekly tier is the genuinely interesting one — most tools in this space force a monthly commitment on a problem that is bursty. Where it holds up weakest is depth beyond design. The evidence doesn't name the underlying AI model, so you can't verify what powers generation, and the validation quality is the thing you're really buying — worth testing on your own domain before committing to Lifetime. On the marketing side, the homepage says 1K+ schemas created and 4.8/5 from 13 reviews, which is a small sample, and there's a stray 'Start with 5 free schemas' line in the closing CTA that contradicts the 3-schema free tier stated everywhere else. Small thing, but it's the kind of inconsistency worth noticing when a vendor is also selling a $299 one-time plan. For a team already on Postgres and Supabase shipping multiple projects a year, the $19/mo Pro pays for itself in one avoided migration rewrite. For a solo developer who needs one schema, the free tier is probably enough and the Lifetime plan is overkill.

Real-world workflow fit
Concrete scenarios for the personas Structa actually fits — and what changes day-one when you adopt it.
You describe your app in plain English on the Structa canvas, accept the generated schema, then drag a couple of tables into a cleaner layout and connect the relationships the AI missed.
Outcome: You leave with a validated schema, an ER diagram you can share with a co-founder, and a migration file ready to run — without a single re-prompt.
You paste in the new feature's requirements, let Structa generate the tables, run validation to catch missing constraints and indexes, then use AI Fix on the two relationship errors it flags before exporting to SQL.
Outcome: The migration ships without the broken foreign keys you'd normally catch in staging after a manual ChatGPT cleanup.
You design the schema in a shared team workspace, let a teammate review the ER diagram on the canvas, then deploy to Supabase in one click with smart migrations after sign-off.
Outcome: Centralized billing and role management mean the lead owns the subscription while the team iterates on the same design instead of trading SQL files.
Use Cases

- Iterate on a schema design interactively without rewriting SQL.
- Collaborate with a team on a shared database design workspace.
- Catch broken relationships and missing constraints before exporting to a live database.
Models Under the Hood
as of 2026-09-14
Limitations
- The free tier allows 3 schemas total and 1 export total; unlimited SQL exports require a paid plan.
- Deploying to Supabase is a paid-tier feature with iterative updates, and team features require the seat-based Team plan at $25/seat/month.
- AI Fix and full validation are also paid-tier.
- The underlying AI model is not named anywhere in the vendor's public copy, so you cannot verify which model powers generation before buying.
- Structa is a design layer: it exports Prisma schemas but does not replace Prisma as your runtime ORM, and it does not host or run your database.
- The homepage is internally inconsistent on the free allowance (3 schemas in the main copy, '5 free schemas' in the closing CTA), so confirm the current cap before relying on it.

Where the pricing makes sense
The company stage and team size where Structa's pricing actually pencils out — and where peers do it cheaper.
Structa's pricing spreads across the whole range: free for 3 schemas, $4.99/week for a burst of project work, $19/mo Pro for multiple projects a month, $299 one-time for lifetime ownership, and $25/seat/month for teams. It sits well below enterprise data-modeling suites and only slightly above a raw ChatGPT subscription you'd otherwise be repairing by hand. Solo developers who shipped one project will find Pro unnecessary; anyone shipping several a year will find the $19/mo tier cheap against
Setup time & first value
How long it actually takes to get something useful out of Structa — broken out by persona, not the marketing-page minute.
Solo developer: roughly 30 seconds to a first generated schema — the vendor advertises 'No credit card • No account required • Start in 30 seconds', and the design flow starts from a plain-English description rather than a blank canvas. Teams: slightly longer, since the Team workspace requires seat setup and role assignment before members can collaborate, but the vendor describes it as self-serve
Switching to or from Structa
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From ChatGPT or a raw LLM prompt: bring the app description you were already prompting with, generate a validated schema on the canvas instead, and export SQL or Prisma without hand-fixing constraints.
- →From a hand-drawn ER diagram or whiteboard design: rebuild the tables on the Structa canvas, then export migration files rather than transcribing the diagram into SQL by hand.
- →From Prisma's own tooling: keep Prisma as your runtime ORM and use Structa upstream to design the models, then export the Prisma schema directly.
- ↗To Prisma: export the Prisma schema Structa generates and continue using Prisma for migrations and runtime queries.
- ↗To plain SQL: export SQL for any database and run it directly against PostgreSQL, MySQL, or your target engine.
- ↗To Supabase: deploy directly from Structa with smart migrations if you want the design applied to a live Supabase project.
