## Developer tools

- [Flecha](https://apps.oprimo.dev/en/flecha/) ([pt-BR](https://apps.oprimo.dev/flecha/)): Flecha is a Chromium browser for macOS, Windows and Linux with an Arc-style vertical sidebar, Spaces, Peek and split view, rebuilt from scratch, and a command bar that understands gh 482, npm, mdn, JWTs and staging URLs. It shows your dev servers in the sidebar, moves a page between local, staging and production with one key, and lets agents like Claude Code and Cursor use your tabs over MCP.
- [FDBK](https://apps.oprimo.dev/en/fdbk/) ([pt-BR](https://apps.oprimo.dev/fdbk/)): FDBK is a feedback board for product teams: each product gets a public board where users suggest ideas, report bugs and vote without an account, with a roadmap and changelog that update as the team changes statuses. It's for software companies that want feedback for several products in one inbox, at a flat price that never grows with users or votes.
- [Semaphore](https://apps.oprimo.dev/en/semaphore/) ([pt-BR](https://apps.oprimo.dev/semaphore/)): Semaphore is a floating traffic light that shows whether your AI coding agent is idle, thinking or writing files, without switching windows. It works with Claude Code, Cursor, Codex, Gemini CLI and Copilot CLI, and has a Stream Deck plugin.
- [Primo Brutality UI](https://apps.oprimo.dev/en/primo-brutality/) ([pt-BR](https://apps.oprimo.dev/primo-brutality/)): primo-brutality is a neo-brutalist UI component library for React Native and Expo: thick borders, hard shadows and bold colors. It ships on npm as @primo-brutality/ui and is styled with NativeWind v4 classes.
- [Primo UI](https://apps.oprimo.dev/en/primo-ui/) ([pt-BR](https://apps.oprimo.dev/primo-ui/)): primo-ui is a React design system built with Stitches and Radix UI, with design tokens and Storybook docs. It is an unfinished learning project, as the repo description says: 9 components are done and more are on a to-do list.
- [Esqueletão](https://apps.oprimo.dev/en/esqueletao/) ([pt-BR](https://apps.oprimo.dev/esqueletao/)): Esqueletao is a skeleton loading library for React Native and Expo, with shimmer and pulse animations powered by Reanimated. You build placeholders with the Skeleton component and set a global theme through SkeletonProvider.
- [Primotion](https://apps.oprimo.dev/en/primotion/) ([pt-BR](https://apps.oprimo.dev/primotion/)): Primotion is a lightweight React library that animates any element with spring physics. It ships a useSpring hook and Spring, Animated, FadeIn and SlideIn components, all driven by requestAnimationFrame.
