Platform services
EXO's components. Each app picks the ones it needs, so apps skip basic plumbing.
These services are EXO's components. EXO is mission control for launching apps: people build apps
on EXO, and each app picks the components it needs. It is modular, and no app uses everything. An
app declares its components in project.yaml as a top-level components list (ADR 0013),
and EXO Verify Level 1 checks that each declared component is wired. Core components are the
ones most apps need; specialty components are the ones only some apps need
(overview). A starter kit is a saved set
of components that new apps can start from. Each service follows the same
pattern: Exo owns the platform relationship, keys, and schema, and apps call one Exo contract.
Swapping the platform behind a service is an Exo change, not an app change
(tenet 3).
| Service | Dimension | Decision | Status | Platform behind it |
|---|---|---|---|---|
| Exo Key | Identity | ADR 0004 | Live on staging | Convex Auth v2 |
| EXO Verify | Continuous integration | ADR 0005 (on main) | Accepted; not built | Vitest, Playwright, Railway workers, open-source review engine |
| Exo Analyze | Analytics | ADR 0006 (on main) | Accepted; planned | PostHog adapter |
| Exo Deploy | Deploy | ADR 0007 (on main) | Web live; mobile accepted, planned | Railway; Expo; EAS optional |
| Exo Rank (code: router) | AI | AI routing | Endpoint live; routing built | Convex AI Gateway, Arch-Router; Artificial Analysis TBD; TypeSafe dormant |
How they join up
The services are designed to compose into one per-App cost-to-serve record:
- Exo Key supplies the sign-up step of the Exo Analyze funnel.
- Exo Rank records every model call in
exoAiBrokerJobs. - EXO Verify sends its AI review calls through Exo Rank and records its cost per App.
- Exo Deploy bakes the Exo Analyze SDK and Exo Key native sign-in into the mobile template.
- Exo Analyze joins visits, sign-ups, payments, and cost to serve into per-App unit economics.
See cost and unit economics for which of these joins exist today.

12 · Artificial intelligence
Apps send prompts to Exo Router, Exo's smart model routing. It scores how hard each task is and picks the least costly capable model through the Convex AI Gateway.
Exo Key
Exo is the only OAuth client and identity provider; Apps are relying parties that receive app-scoped RS256 tokens.
