Releasing to 10% of users without watching metrics is just gambling at a smaller scale. Here's how to connect flag evaluations to your observability stack — so you know when to expand, and when to pull back.
Percentage rollouts control how many users see a feature. Targeting rules control which users see it — by plan tier, beta opt-in, org ID, or any attribute you pass. Here's how to use them.
Database migrations are one of the riskiest parts of a deployment. The expand-contract pattern with feature flags decouples schema changes from application releases — so you can migrate safely, roll back instantly, and never touch the database in anger again.
Manual flag toggles after deploys break your automation story. Wire the Featureflow API into your pipeline and make flag lifecycle a first-class deployment step — no dashboards, no humans in the loop.
Synchronized deployments across multiple services kill the independence microservices promise. Feature flags give you a single control plane to release features across the stack — without locking services together.
When something breaks in production, a kill switch turns off the offending feature in seconds — no redeploy, no hotfix, no 2am war room. Here's how to build them right.
Every redesign starts as a guess. Feature flags give you consistent user bucketing and percentage-based traffic splits — so you can run experiments without adding another tool to your stack.
The canary in a coal mine gave enough warning to get out. Canary releases work the same way — expose new code to a small slice of real traffic, watch for problems, and expand only when you're confident.
Naming, lifecycle management, boundary isolation, observability, and rollback planning — the five practices every engineering team using feature flags should internalize.
In regulated industries, uncontrolled feature releases create audit gaps. Feature flags give you traceable, reversible releases with a clear record of who changed what, when, and for whom.
Long-lived branches create merge hell. Trunk-based development with feature flags lets every engineer commit to main daily — and still ship safely.
Flags that never get cleaned up become the worst kind of tech debt — invisible, dangerous, and nobody knows what they do. Here's a practical guide to naming, auditing, and retiring flags before they rot.
Agentic AI ships code to production at sprint speed—but without guardrails, velocity becomes risk. Here's how feature flags keep humans in control.
All Featureflow users know that if you want to add a new feature to your React application, you can put it behind a feature flag, release silently, then choose your rollout plan to suit.
In Agile methodology, Feature Driven Development (FDD) is an iterative and incremental framework designed around focusing on feature development in 2 week sprints.
Got something big to release? Jittery knees? Not sure how the system or the public will react? Gradual rollouts can be your friend and they can be easier than you'd expect.
Betas are an important approach to ensuring you release the right stuff to your customers. Betas are usually pre-released to a subset of customers with a feedback mechanism.
Continuous delivery is a software practice which enables you to get your software to customers in small, quick increments. It is a core part of lean and agile methodologies.
