Convex
Convex is a TypeScript-native serverless backend platform with a reactive document database, server functions, and real-time subscriptions. Application logic runs as Convex functions (queries, mutations, actions) deployed to Convex's cloud, with automatic reactivity propagating database changes to subscribed clients.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Secrets stored in Convex environment variables encrypted at rest. Auth enforced at function level — developers must implement authorization logic inside functions. No row-level security system built in; security is coded into function logic.
⚡ Reliability
Best When
You are building a TypeScript-native agent or full-stack application that needs reactive real-time state synchronization, transactional mutations, and serverless compute in a single cohesive platform.
Avoid When
Your agent stack is Python-based, you need a traditional REST API, or you need complex relational queries. Convex's query language is limited compared to SQL.
Use Cases
- • Building real-time collaborative agent applications where state must sync across multiple clients
- • Running TypeScript-native backend logic as Convex actions triggered by agent workflows
- • Using Convex's transactional mutations to ensure agent state changes are atomic and consistent
- • Storing and querying agent conversation history with reactive updates to a UI
- • Scheduling background jobs and cron tasks for agent orchestration via Convex scheduler
- • Building full-stack TypeScript agent apps where frontend and backend share type-safe function signatures
Not For
- • Non-TypeScript/JavaScript backends — Python, Go, and other language agents cannot use Convex directly
- • Traditional REST or GraphQL API consumers — Convex uses its own function invocation protocol
- • Complex SQL analytics or joins across large datasets
- • Agent-to-agent communication patterns that don't fit the client-server Convex model
Interface
Authentication
Convex integrates with Clerk, Auth0, and other JWT-issuing auth providers. Auth identity is extracted from the JWT and available inside Convex functions as ctx.auth. No built-in API key auth — agents must authenticate through a configured JWT provider or use Convex's HTTP Actions for custom auth.
Pricing
Free tier is genuinely useful for development and small applications. Function call pricing scales predictably. No per-seat pricing — cost is based purely on usage.
Agent Metadata
Known Gotchas
- ⚠ No REST API — agents must use the Convex TypeScript client or HTTP Actions as a bridge
- ⚠ Queries and mutations have strict 1-second execution time limit — long-running agent logic must use Actions
- ⚠ Convex Actions (which can call external APIs) cannot directly read/write the database without going through mutations
- ⚠ Schema is TypeScript-defined and type-checked — schema migrations require careful handling
- ⚠ No support for Python, Go, or other non-JS/TS runtimes natively
- ⚠ Real-time subscriptions require a persistent connection — not suitable for serverless polling agents
- ⚠ Function names are file-path based — refactoring file structure changes API surface
