Structa
Structa converts plain English into validated SQL and Prisma schemas with a visual ER diagram editor.
The validation loop plus the diagram editor is the part a chat window genuinely can't replicate, and Pro at $19/mo pays for itself the first time you avoid a hallucinated foreign key. Buy it if you're shipping more than one project a year. Skip it if what you actually need is a running database, a replacement ORM, or a no-code backend — Structa designs schemas and stops there.

Skip Structa if you need a hosted database or a replacement ORM — it designs and exports schemas (SQL, Prisma, migrations) and deploys to Supabase, but Prisma still runs your queries and nothing here hosts your data.
The free tier's 3 schemas and 1 export are a total lifetime allowance, not monthly, so the second project you export pushes you onto a paid plan.
At $4.99/week for a time-boxed project, $19/mo Pro for high-volume builders, $299 one-time for long-term owners and $25/seat/month for teams, Structa sits in the low-cost dev-tooling band — cheaper than a full design-plus-ORM stack for a single project, and priced below most seat-based schema or data-modeling suites. The Weekly tier is the genuinely unusual option: real value if you have one active project and no ongoing need.

What is Structa?
Structa — Structa converts plain English into validated SQL and Prisma schemas with a visual ER diagram editor. Best for Full-stack developers who need a validated schema without prompt engineering, Indie hackers prototyping an app backend from a plain-English idea, Backend teams reviewing relationships on a shared visual canvas. Free to start; paid plans from $19/mo.
Structa is an AI database schema generator for developers who want a working database design out of a plain-English app description, not a chat transcript full of broken SQL. Describe the app and it produces tables, fields, foreign keys, indexes and constraints, validates them, then hands you a visual canvas where you drag, drop and connect tables like blocks. Editing happens on the diagram itself, so fixing a wrong relationship is a drag rather than another prompt and a full regeneration. The workflow splits into three entry points: a Database Schema Generator (SQL + Prisma + ERD), an AI SQL Generator that turns plain English into SQL, and a Prisma Schema Generator. Output covers SQL for any database, Prisma schemas, migration files and shareable ER diagrams. One-click deployment to Supabase applies smart migrations, and AI Fix patches schema errors in place instead of rebuilding the whole design. Validation warnings catch problem constraints, indexes and relationships before they reach your database. Getting in is low-friction — no credit card or account required to start. Paid plans unlock a premium AI model, unlimited SQL exports, unlimited AI chat and AI Fix with full validation. Team plans add a shared workspace with role management and centralized owner billing. Structa sits upstream of your ORM and your database: it is a design layer, not a Prisma replacement and not a hosted Postgres. That makes it a complement to Supabase and Prisma rather than a competitor to either, and a different category from no-code backend builders.

Behind the verdict
Where Structa earns its keep is the moment a generated schema is almost right. ChatGPT will give you plausible SQL; getting it to fix one bad relationship usually means re-prompting and hoping, and you end up diffing two walls of text. Structa's answer is to put the schema on a canvas and let you drag the edge. That's a small idea and it kills a specific kind of afternoon. We'd reach for this when the schema is the deliverable — a new app backend, a Supabase project you're about to migrate, or a Prisma model set you want reviewed by someone who thinks in diagrams. The validation warnings for constraints and indexes are the quiet feature that matters most, because those are exactly what language models get wrong. When to pass: if you need something running at the end of the session. Structa exports SQL, Prisma schemas and migration files and deploys to Supabase, but Prisma still runs your app at runtime and Supabase still hosts your data. Budget for that separation if you were hoping for one tool. The closest alternative isn't another AI tool — it's your existing chat assistant plus an ERD tool, which costs nothing extra but leaves you hand-fixing constraints. Structa's whole pitch is collapsing those two steps. For one throwaway schema, the free entry point is enough to judge whether that's worth paying for. Pricing caveat: plans are priced per project sprint rather than per seat at the low end, so a team of five shouldn't assume the individual Pro tier covers them. Check the current plan terms before committing a group.
Models under the hood
as of 2026-10-30
Limitations
- The free tier allows 3 schemas total and 1 export total; unlimited SQL exports require a paid plan.
- Deploying to Supabase with iterative updates is a Pro feature, and team features require the seat-based Team plan.
- Structa is a design layer: it exports schemas and deploys to Supabase but does not host or run your database.
- The underlying AI model is not named anywhere in the vendor's public copy — paid tiers advertise a "Premium AI model" without identifying it — so you cannot verify which model powers generation before buying.

GeneratedReal-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, Structa generates tables, relationships, constraints and indexes on the visual canvas, you drag a couple of fields into place, run validation to catch a broken foreign key, then export the Prisma schema straight into your repo and deploy to Supabase with smart migrations.
Outcome: A working backend schema without prompt engineering or hand-fixing hallucinated SQL, produced inside a single session rather than an evening of chat iterations.
You paste in or describe the current data model, Structa renders it as an ER diagram you can share via link with the rest of the team, then you edit fields and relationships on the canvas and export updated migration files to apply the changes.
Outcome: A shared visual source of truth for the schema and migration files that match it, instead of a whiteboard photo and a stale SQL dump.
The team moves onto a Team workspace at $25/seat/month, the lead holds owner billing and role management, and members iterate on the shared schema with AI Fix and full validation catching relationship errors before anything reaches production.
Outcome: Multiple developers revising one canonical schema that stays consistent, with a single invoice and clear ownership of who can change what.
Use cases
- Generate a complete database schema for a new SaaS app from a brief description.
- Visualize and edit existing schema relationships with an ER diagram.
- Export a Prisma schema directly from a natural language prompt.
- Deploy a designed schema to Supabase with one click.
- 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.
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.
Indie hackers and full-stack developers: first value in about 30 seconds, since the vendor advertises no signup required — you describe your app and get a schema on the canvas immediately. Teams: plan on the same 30 seconds for the first schema plus however long your workspace invite, role assignment and owner-billing setup takes to clear internally, since Team is a self-serve seat plan.
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: describe the same app in plain English in Structa, then use validation and AI Fix to repair the constraints and relationships the chat output hallucinated.
- →From a whiteboard or hand-drawn ERD: rebuild the tables on the visual canvas and export SQL, migration files or a Prisma schema that matches the drawing.
- →From a raw SQL dump or existing schema: describe or recreate the structure in Structa, then export migration files and deploy to Supabase with smart migrations.
- →From Prisma's own tooling: keep Prisma as your runtime layer and use Structa upstream for the design, validation and ER diagram stage it doesn't cover.
- ↗To a hand-maintained SQL project: export SQL or migration files and version them in your repository without a visual design layer.
- ↗To Prisma tooling: export the Prisma schema and let Prisma's own CLI handle generation, migrations and client code from there.
- ↗To a managed backend platform: use Structa to settle the schema, then move the design into a hosted backend that runs it, since Structa itself does not host your database.
