Tacobase vs Convex
All the Reactivity, None of the Boilerplate
Realtime data without schema files, server functions, or third-party auth.
Convex offers powerful reactive queries, but requires you to define schemas, write server-side functions, and bring your own auth provider. tacobase gives you realtime data, built-in auth, and auto-creating collections with a standard REST API.
What is Convex?
Convex is a reactive backend platform that provides a document database with automatic realtime updates, server functions, and file storage. It uses a custom query language and requires schema definitions and server-side query/mutation functions. Auth requires a third-party integration like Clerk or Auth0.

Why Developers Choose Tacobase
No Custom Query Language
Convex requires you to learn its own query builder and define server-side query/mutation functions. tacobase uses simple, familiar filter strings you can write inline.
Built-In Authentication
Convex has no built-in auth — you must integrate Clerk, Auth0, or roll your own. tacobase ships with email/password and OAuth out of the box.
No Schema Boilerplate
Convex requires a schema definition file and separate query/mutation functions before you can read or write data. tacobase collections auto-create on first write.
Self-Hostable & Open Source
tacobase is fully open source and can be self-hosted anywhere. Convex is a proprietary, cloud-only platform with no self-hosting option.
Standard REST API
tacobase exposes a REST API for every collection, usable from any language or tool. Convex requires its own client libraries and server functions.
Simpler Pricing
tacobase has flat, predictable plans starting at $7/mo. Convex pricing is usage-based and starts at $25/mo for the Pro plan.
Frequently Asked Questions
Common questions about Tacobase vs Convex
How does tacobase compare to Convex for realtime?
Both platforms support realtime data. Convex makes every query reactive by default through its custom query system. tacobase uses WebSocket subscriptions you can add to any collection. The key difference is tacobase doesn't require you to write server-side query functions — you subscribe directly from the client.
Does tacobase require a third-party auth provider?
No. tacobase ships with built-in email/password authentication and OAuth provider support. Convex has no built-in auth and requires you to integrate Clerk, Auth0, or another third-party auth service, adding cost and complexity.
Can I self-host tacobase unlike Convex?
Yes. tacobase is fully open source and self-hostable as a single binary. Convex is a proprietary cloud-only platform with no self-hosting option, creating vendor lock-in.
Why doesn't tacobase use a custom query language?
tacobase uses simple filter strings (e.g., 'published = true') and a REST API, which means any developer or AI tool can use it immediately. Convex's custom query builder requires learning a new API and writing server-side functions for every data access pattern.
Is tacobase good for React apps like Convex?
Yes. tacobase has a dedicated React package (@tacobase/react) with hooks like useCollection and useAuth, plus a TacoProvider component. You get the same React-first developer experience without the schema boilerplate.
