Is APILens really free?
Yes — the Hobby tier is free forever, with no credit card required. Upgrade to Starter, Pro, or Scale as your traffic and team grow.
What frameworks does APILens support?
Express.js and Fastify. Both are supported via the auto-api-observe npm package with zero configuration.
Which databases does APILens profile automatically?
pg, mysql2, mongoose, prisma, knex, sequelize, ioredis, and better-sqlite3 — all profiled automatically with zero code changes.
Does APILens add latency to my API?
Roughly 1–1.5ms average overhead per request, measured with a controlled benchmark (autocannon, 50 concurrent connections, ~10,000 req/sec) rather than estimated. APILens uses async, non-blocking hooks and a buffered log writer — real routes doing actual work see a smaller proportional overhead than this synthetic worst-case test.
