Tutorials

Goal-oriented, step-by-step walkthroughs. Each tutorial starts from a working setup and builds one realistic scenario end to end — follow the chapters in order within a track.

New to exd? The quickstart on the home page takes you from zero to a first evaluated flag in about five minutes. These tutorials pick up from there.

Tutorial What you'll build

Harden your workflow Turn ad-hoc flag edits into a reviewable, testable, observable change process. Six chapters on one realistic flag — a three-variant string with a percentage-bucketed A/B/C rollout: define the flag namespace, lint on every commit and PR, codegen typed context structs, generate fixture-driven tests, ship safely with the testing rollout workflow, and troubleshoot real-user issues with exd eval.
