The measurement of how people use a product — events, funnels, retention, and cohorts — to understand behavior and improve outcomes, as opposed to page-view web analytics. See Analytics →
A switch in code that turns a feature on or off, or targets it to a cohort, without shipping a new release. Used for staged rollouts, kill switches, and A/B tests. See Switch →
Server-controlled configuration values — copy, prices, thresholds, UI — that a live app fetches at runtime, so they can change without an app-store release. See Remote Config →
A reconstructed playback of a user's session — the screens, taps, and events they experienced — used to see exactly what happened before a bug, drop-off, or conversion. See Analytics →
An over-the-air update that ships new interpreted code (JavaScript for React Native, Dart for Flutter) to installed apps without an App Store or Play Store review cycle. See Deploy →
Automatic capture and grouping of app crashes and unhandled errors, with the stack trace, device context, and the release that introduced them, so incidents can be triaged fast. See Catch →
A view of how many users complete each step of a multi-step flow (e.g. sign-up → activate → purchase), revealing where people drop off. See Analytics →
A measure of how many users return over time after a first action, usually shown as a cohort curve — the clearest signal of durable product value. See Analytics →
A group of users sharing a trait or behavior (e.g. "signed up in March" or "used checkout"), used to compare behavior and target flags, surveys, and config. See Analytics →
A feature flag configured to instantly disable a feature in production — the fastest way to stop a bad release from affecting users without a rollback. See Switch →
Releasing a change to a small percentage of users first, watching the metrics, then expanding — so a regression is caught at 5% rather than 100%. See Deploy →
A controlled experiment that shows different variants to different cohorts and measures which performs better against a defined success metric. See Switch →
A short survey shown inside the product, triggered by user behavior, to capture feedback (NPS, CSAT, or open text) in the exact context it's about. See Pulse →
Objectives and Key Results — a goal-setting framework pairing a qualitative objective with measurable key results, used to align strategy with execution. See Vision →
A model where the core product is open source and self-hostable, while commercial modules and hosting are sold on top — so users own the foundation and can't be locked in. See Sankofa OS →
Running software on your own infrastructure instead of a vendor's cloud, so your data never leaves your control — essential for regulated or air-gapped environments. See self-hosting →
Automatically reverting a release when a monitored signal (like crash rate) breaches a threshold, so a bad deploy heals itself without a human in the loop. See Catch →
