Your app got slow.
Now you'll know why.

You built something fast. Then it started dragging. Nightshift watches your database and your requests, finds the slow parts, and points at the exact line of code — with a fix you can actually read.

Reads your database. Never writes. Never touches your code.

How it works

  1. 01

    Connect, read-only

    A read-only database user and read-only repo access. Two minutes. No SDK, no code changes.

  2. 02

    It watches

    Slow queries and slow requests, caught in your real app — then measured properly, not guessed at.

  3. 03

    It finds the cause

    Not “this is slow.” The exact file and line, and what set it off — a route, a job, a loop.

  4. 04

    It suggests a fix

    You read it. You decide. It never merges anything. It just does the boring detective work first.

Built because my own app got slow, and the tools were either toys or built for people with an SRE on staff. This is the one I wanted. Maybe you want it too.

See what's slow.
