SchemaStack is a platform — we serve a few distinct audiences well. You're probably one of these.
You're a developer or agency delivering a collaborative data tool to a client. You need spreadsheet UX, guest access, and a REST API — without hosting your client's data. Custom-building takes weeks you don't have; Retool is internal-only; Airtable sends the data to a place your client can't approve.
Airtable's linked records hit a wall. You need real relationships — M2M, 1:N, composite keys — and cross-field validation. And you'd rather the data live in your own Postgres than another vendor's cloud.
Product catalogs, inventory, vendor lists, configuration — in Google Sheets or Airtable, and it's breaking. You need validation, collaboration, and a setup IT won't reject on data-residency grounds.
Contentful is expensive, Strapi means self-hosting, Sanity locks you in. You want structured content with a REST API — living in your own Postgres, where you control backups, residency, and exit.
The common thread: managed software, self-owned data.
Connect your database or use managed hosting — either way, your data stays yours
SchemaStack connects to your existing database and only stores metadata. Your business data never leaves your infrastructure — no vendor lock-in, ever.
Don't want to run Postgres yourself? Use our Managed RDS or Enterprise ZFS hosting. Even managed, your database is dedicated to your org — no shared multi-tenant database, no data commingling, portable out anytime.
View and edit your data through a familiar interface with real-time collaboration. Create custom views with filters, sorting, and presets for every workflow.
Every workspace automatically gets a full REST API with CRUD operations, filtering, pagination, and Swagger docs. No code generation — the API is live as soon as your schema is defined.
Define entities, columns, types, and constraints. Column validation and cross-field rules catch data problems before they enter your system.
Each workspace gets its own database connection — no cross-tenant data commingling. Granular permissions, member roles, and external guest access built in.
Describe your data in plain English and Schema Advisor suggests a validated schema — entities, columns, constraints, relationships. Edit it, keep it, or ignore it. You're never locked into AI output.
Create guest links for clients, contractors, or auditors — they see only the view you share, with read or edit access. Time-limited, revocable, no org membership required.
