Battle-test AI coding models side by side
Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
Watch models construct web apps and websites live, so you can see process and output, not just the final file.
Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
Track which coding models accumulate the most wins over time to identify consistently strong performers.
Reactive TypeScript backend with database, functions and AI gateway
Document store with ACID transactions that pushes live updates to subscribed clients automatically, no manual invalidation needed.
Schema, queries, mutations, actions and HTTP endpoints are written in TypeScript with end-to-end type safety from client to database.
Open-source modular building blocks such as Agent, Workflow, Workpool, Stripe, Resend and Twilio that drop into your app.
Call major language models through one unified API and billing path instead of managing separate provider credentials.
SpecialistAI app builder that converts natural language into full-stack web applications, but with less backend database control.


SpecialistAI-native code editor for multi-file development, requiring manual backend setup compared to Convex's managed platform.

SpecialistNo-code AI development platform turning prompts into applications, but less suited for custom backend TypeScript code.
