Flipt v2▲178
Hey all, I'm the founder of Flipt, an open-source (https://github.com/flipt-io/flipt) feature flag tool that I (and others) have been working on for the past few years. About a year or two ago we added support for serving flag state from various non-relational declarative stores like Git, OCI, Object Store, etc. Many of our users came to love the git-backed storage, as it allows them to keep their feature flags close to their code in there organization's repos. But they had one (rather large) ask, and that was the ability to use the UI to manage flag state changes and…

Featurevisor – Git-based feature flags and experiments management▲48
Why? - Decouple application deployment from releases How it works: - Make changes to your features and segments (YAMLs) via Pull Requests - Generate datafile (JSON file) in CI/CD workflow and upload to your CDN - Fetch datafile in your application runtime and consume with SDKs Supports: - Feature flags: boolean flags - Experimentation: a/b tests - Segments: targeting traffic with conditions - Variables: namespaced under each feature and conditional - Gradual rollouts: avoid big bang releases, go from 0% to 100% - Consistent bucketing: same user sees same variation - Multiple…

Atono▲189
We kept asking "why did we build it this way?" and spending 20 minutes hunting through Jira, Slack, and GitHub for answers. It was a symptom of a bigger "Jira-problem". So we built Atono (https://atono.io). The idea: Stories that don't die when you ship. Everything - requirements, code changes, bugs, decisions - stays in one place. Our take (might not be for everyone): -Feature flags live in the story, not another tool -Feature engagement for you to see if people use what you built -Context > process What's in it: -Toggle feature flags right in the story -See usage graphs without…

FFlags – Feature flags as code, served from the edge▲42
Hi HN, I'm the creator of FFlags. I built this because I wanted a feature flagging system that gave me the performance and reliability of an enterprise-scale solution without the months of dev time or the vendor lock-in. The core ideas are: 1. Feature Flags as Code: You define your flag logic in TypeScript. This lets you write complex rules, which felt more natural as a developer myself than using a complex UI for logic. 2. Open Standard: The platform is built on the OpenFeature standard (specifically the Remote Evaluation Protocol). The goal is to avoid vendor lock-in and the usual…
