# Free Open-Source Alternatives to Photoshop, Excel and Slack You Can Run Yourself > Source: > Published: 2026-10-26 01:10:40+00:00 *This article was drafted with AI assistance and fact-checked against the project's README.* Photoshop, Excel and Slack all come with a monthly bill. The **HeyPuter/everything** repo rebuilds free, open-source alternatives to proprietary software like these from scratch, under the MIT license. It has 3.5k stars on GitHub. A few of the apps and what they stand in for, as listed in the README: It also includes games, such as Chess and a Sudoku with 4 difficulty levels and daily puzzles. Every app in the README table has a **Try it** link and a **Source** link, so you can open an app in the browser before installing anything. You need **Node.js 22.12 or newer**. Then run the four commands from the README, swapping `[app-name]` for the app folder you want (for example `spreadsheet`): ``` git clone https://github.com/HeyPuter/everything.git cd everything/src/[app-name] npm install npm run dev ``` Third-party libraries included in the repo may have their own licenses. Check them before you reuse code in your own project.
