About
Flagsmith is an open-source feature flagging and remote configuration platform that enables engineering teams to deploy code continuously and control feature releases, A/B tests, and configuration changes through feature flags rather than synchronized deployments — offering a self-hosted or cloud-hosted alternative to LaunchDarkly at dramatically lower cost. Fully bootstrapped with $229,000 raised from Polychrome Capital, Flagsmith reached $1 million+ ARR by July 2024 serving enterprise clients including Citi Bank and UnitedHealth Group.
Open-source offline-first API client with git-native Bru file storage; solo-founded, declined 8 VC offers, competing with Postman and Insomnia for developers seeking privacy-respecting local API testing tooling.
About
Bruno is an open-source API client and testing tool — a lightweight, offline-first, git-friendly alternative to Postman and Insomnia — enabling developers to explore, test, and document APIs with collections stored as plain-text Bru files in the project filesystem rather than in cloud-synced proprietary formats. Created by a solo founder in 2022 and growing to a 9-person team by late 2024, Bruno operates with an unusual philosophy: the founder publicly declined 8 venture capital offers to preserve product freedom and build toward profitability, with the core Bruno client remaining free and open-source (MIT license) while the Golden Edition provides enterprise features for commercial revenue. Pro and Ultimate paid editions launched in 2024.
