Compare · Reactive backend for TypeScript developers
Aaly vs Convex
Convex is a reactive backend built around TypeScript functions you write, with realtime subscriptions on by default and tight editor integration. It's leaning hard into the AI-agent story and ships its own MCP server. Of the products here, it's the one built most recently with agents in mind.
Choose Convex instead if
- ·You want realtime-by-default: live queries that push updates to clients automatically. Aaly has no realtime today.
- ·Your team wants to write and own TypeScript functions directly, with full control over server-side logic.
- ·You're already deep in the TypeScript ecosystem and want that level of editor and type integration.
Where Aaly differs
- →This is the closest comparison here, and the one worth reading carefully. Convex's unit of work is still code. An agent (or a person) writes TypeScript functions that Convex runs. Aaly's unit of work is a definition; there is no function to write, review, or regenerate when the schema changes.
- →That's the same argument Aaly's Mechanism section makes generally, applied to the one competitor already courting the same agent-builder audience: generated code, however good the tooling around it, is still code somebody has to get right on every change.
- →Convex bills $25 per developer seat on its Professional plan. Aaly has no per-seat charge at any band.
| Convex | Aaly | |
|---|---|---|
| Unit of work | TypeScript functions (code) | A definition (data, not code) |
| Realtime | Live queries by default | Not available: poll or bolt on a third party |
| Billing model | $25 / developer seat (Professional) | Usage-based, no per-seat charge |
| Agent MCP support | Yes, a genuine competitor here | Yes: OAuth 2.1 + PKCE, no key to manage |
| What changes on a schema edit | Functions may need rewriting | Nothing: the API is served from the definition |
