Capy – A Git-style platform for managing your team's secrets
Hello HN! We're all spending more and more time making stuff with agents, but I've noticed that one of the things that is the most disconnected from my daily engineering workflow is dealing with secrets and credentials. It often involves a lot of click-ops, copying/pasting, and collaboration, and none of the secrets management products out there have truly scratched that itch. I built Capy to solve this. It's a secrets manager whose entire frontend is a developer CLI, and I find it extremely ergonomic to use by hand. You also don't need to leave the CLI to sign up for and use it! You…
In plain words
Capy is a secrets manager designed for developers who want to manage credentials without leaving the command line. It offers a CLI-based interface for storing and sharing secrets across teams, with version control features similar to Git, including branching and conflict resolution. The tool supports authentication entirely through the terminal and allows teams to push secret versions to source control for collaborative workflows.

Hello HN! We're all spending more and more time making stuff with agents, but I've noticed that one of the things that is the most disconnected from my daily engineering workflow is dealing with secrets and credentials. It often involves a lot of click-ops, copying/pasting, and collaboration, and none of the secrets management products out there have truly scratched that itch. I built Capy to solve this. It's a secrets manager whose entire frontend is a developer CLI, and I find it extremely ergonomic to use by hand. You also don't need to leave the CLI to sign up for and use it! You can install and authenticate without leaving your terminal (or agent) session. It also has very powerful version management with git-like branching and conflict resolution. You can push a version manifest to source control and have collaborators pull a specific version of the secrets at any point in time. The platform itself is extremely secure. It encrypts your local .env files so they can't be read directly. Upon pushing the values to the service, it encrypts them yet again with a service key. That way neither a compromised local machine nor a compromised service alone will result in a leakage. BTW: Since it was released in April, I've been refining it and have evolved the focus a bit. Originally I was going for more TUI and TTY with guided wizards for doing things like deployments, rotations, and connecting services, but I realize that the real future is in making the product work EXTREMELY well with agents. So the next evolution of is a more satisfying Agent ergonomic, and I have been working on something big next on that front. Curious about your thoughts on the idea, execution, and would appreciate any and all feedback!

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
