When Fliq fits

You don't want an event/function framework — you just need to schedule HTTP requests to existing endpoints, with retries, crash recovery, and per-attempt history, controllable by AI agents via MCP (beta), on a simple Postgres-native stack.

When Inngest fits

You're building event-driven workflows — fan-out, concurrency limits, debouncing, multi-step functions — and want to define them as code triggered by events. Inngest is purpose-built for that model.
