Open source in 2025 quietly told a story I keep seeing everywhere else too, which is that the projects that win are the ones that remove frustration from existing workflows.
GitHub published the year's most influential open source projects. The list clusters into a few common themes:
1) "Time-to-shipping" infrastructure is the new moat
Appwrite exists because people are tired of rebuilding the same backend lego set: https://github.com/appwrite/appwrite
GoReleaser exists because release engineering is boring, fragile, and too important to keep doing manually: https://github.com/goreleaser/goreleaser
Homebrew is still the default because onboarding and environment setup still matter more than most teams admit: https://github.com/Homebrew/brew
2) The new browser renaissance is real - but it's mainly about trust
Ladybird is a bet that control, transparency, and a clean-slate architecture are worth the pain. That's not nostalgia. That's a reaction to complexity, security surface area, and platform capture: https://github.com/LadybirdBrowser/ladybird
3) "Developer ergonomics" keeps eating everything
Oh My Zsh and its ecosystem are proof that devs will spend serious time improving their daily loop: https://github.com/ohmyzsh/ohmyzsh
4) Security is shifting from vibes to checklists
OSPSB is interesting because it's not a tool. It's a standardized minimum. That's how ecosystems scale without collapsing under supply-chain risk: https://baseline.openssf.org/
5) Graphics + creative coding keeps powering modern UI
PixiJS (https://github.com/pixijs/pixijs), p5.js (https://github.com/processing/p5.js), and even things like SparkJS (https://github.com/sparkjsdev/spark) are basically the "frontier engines" behind interactive experiences. A lot of "AI demos" still get shipped using these tools.
6) AI is getting smaller and more deployable
Moondream signals the direction: models that fit constraints (size, edge, no GPU dependency) are often more practical than the biggest model on the leaderboard: https://github.com/vikhyat/moondream
7) Organized open source alternatives to Slack and Teams are gaining traction
And then there's Zulip, which I'd file under "boring but correct": structured communication scales better than chaos-chat: https://github.com/zulip/zulip/
