A self-hosted pair programming service for collaboratively editing local files over a web UI using operational transforms.
Leaps is a pair programming service that allows multiple users to collaboratively edit local files in real-time through a web interface. It uses operational transforms to synchronize changes without collisions, enabling seamless team coding sessions directly from your file system. The service also includes features like safe mode for protecting files and the ability to run build/test commands from the UI.
Developers and teams who need to collaborate on code in real-time, such as remote pair programmers, coding instructors, or small development teams working on shared projects.
Leaps offers a self-hosted, secure alternative to cloud-based pair programming tools, giving teams full control over their files and environment. Its operational transform engine ensures reliable synchronization, and the ability to run commands from the UI streamlines the development workflow without leaving the editor.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Uses operational transforms to ensure zero-collision editing across multiple clients, as highlighted in the README, making it reliable for real-time collaboration without merge conflicts.
Directly edits local files in the background, allowing teams to collaborate on existing codebases without migrating to cloud services, as described in the run section.
Offers a safe mode that stores changes in a separate JSON file until manually committed, preventing accidental file corruption, which is ideal for teams not using version control.
Allows pre-defined commands like linters and builds to be run from the UI, with results broadcast to all users, streamlining workflows without leaving the editor, as shown with the -cmd flag example.
Comes as a single binary with no runtime dependencies, making installation and setup straightforward on supported OSes like OSX and Linux, per the install instructions.
The README explicitly warns that the project is no longer actively maintained, meaning no bug fixes, security updates, or new features, which poses risks for production use.
Only supports ACE, CodeMirror, and Textarea editors, missing integration with popular modern editors like VS Code or Monaco, which reduces flexibility for teams.
Default setup is optimized for LAN use, requiring additional configuration for internet access, and lacks built-in tools for secure remote collaboration over public networks.
Using it as a library requires Go knowledge and custom implementation for authentication and hosting, as noted in the API section, adding overhead for non-Go developers.
