The top 10 most-starred open source projects

Star count is a flawed but useful proxy for adoption. The current top 10:

1

OpenClaw

★ 369.7k
2

opencode

★ 190.0k
3

n8n

Fair-code workflow automation platform

★ 187.1k
4

AutoGPT

AutoGPT is the vision of accessible AI for everyone

★ 184.1k
5

Ollama

★ 160.4k
8

Langflow

★ 147.8k
9

Dify

AI-powered app creation without coding complexities

★ 140.6k
10

Next.js

The React Framework for the Web

★ 139.3k

License distribution

MIT and Apache 2.0 still dominate, but AGPL has grown sharply as project maintainers reach for stronger copyleft to defend against cloud-extraction. BSL and SSPL remain niche but high-profile.

NOASSERTION205 (23.9%)
MIT201 (23.5%)
Apache-2.0177 (20.7%)
AGPL-3.0171 (20.0%)
GPL-3.043 (5.0%)

GPL-2.010 (1.2%)
BSD-3-Clause9 (1.1%)
BSD-2-Clause3 (0.4%)
LGPL-2.13 (0.4%)

Language distribution

TypeScript continues its march. Rust is overrepresented relative to its general-purpose use — infrastructure tools love it. Python dominates the AI category.

Where the energy is

By project count + combined stars per category, AI & ML and Developer Tools lead by a wide margin. Look at the per-project star average to see which categories have density (a few mega-projects) vs breadth (many smaller ones):

What we're watching in 2026

  • —Continued relicensing pressure. Expect another 2-3 prominent projects to move from permissive to BSL/SSPL/FSL. The pattern is well-established.
  • —AI infrastructure consolidation. Many AI agent frameworks. Expect winners to emerge — likely the ones with strong open governance, not the VC-backed ones.
  • —Self-hosted apps growing. Cloud cost discipline + privacy concerns are driving renewed interest in self-hosted Notion/Slack/Airtable alternatives. See our awesome list →
  • —Maintainer burnout signals. Our abandonment monitoring catches projects going quiet. Current list →
