Hottest Repos
tinyhumansai/openhuman — 12,771 stars (+1,694 today). Day 7: 5x in one week. From 2.5K to 12.8K — the "personal AI super intelligence" is the fastest-growing repo of the month. Still accelerating. The Rust-powered, Obsidian-compatible agent with 118+ OAuth integrations has clearly found product-market fit. https://github.com/tinyhumansai/openhuman
tech-leads-club/agent-skills — 3,429 stars (+923 today). NEW: The "secure npm" for agent skills. Positions itself against the wild west of skill marketplaces — citing a Snyk report that 13.4% of marketplace skills contain critical vulnerabilities. Hardened registry with static analysis, content hashing, and symlink guards. Supports Claude Code, Antigravity, Cursor, Copilot. The security angle is the differentiator. https://github.com/tech-leads-club/agent-skills
oven-sh/bun — 91,670 stars (+908 today). Bun's biggest day in months. Nearly 1K stars in a single day for the JS runtime — something dropped or got announced. At 91.7K, the 100K milestone is within reach this summer. https://github.com/oven-sh/bun
mattpocock/skills — 88,655 stars (+18,795 this week). Seventh week of massive growth. From 68K to 89K in a month. Still gaining 2K+/day. At this pace, crosses 100K before May ends. https://github.com/mattpocock/skills
obra/superpowers — 194,996 stars (+9,939 this week). 5K from 200K. The agentic skills framework is days away from becoming the first open-source dev tool to hit 200K stars. 16.8K forks. The gravity well of the entire agent skills ecosystem. https://github.com/obra/superpowers
AI & ML
Anil-matcha/Open-Generative-AI — 14,973 stars (+704 today). NEW: Self-hosted AI video/image studio. 200+ models (Flux, Midjourney, Kling, Sora, Veo), no content filters, MIT licensed. The "uncensored, self-hosted" creative AI space is consolidating around this project. 2.6K forks signal real deployment. https://github.com/Anil-matcha/Open-Generative-AI
rohitg00/agentmemory — 11,135 stars (+6,907 this week). Crossed 11K — still accelerating. From 3.4K to 11K in 10 days. The "agents need persistent memory" thesis is now a category. Background capture, auto-consolidation, context injection across sessions. https://github.com/rohitg00/agentmemory
BigBodyCobain/Shadowbroker — 6,962 stars (+405 today). NEW: OSINT meets AI agents. Real-time geospatial intelligence aggregating 60+ feeds — aircraft ADS-B, maritime AIS, satellites, CCTV, mesh radio, earthquake sensors — onto one map. The wild part: an HMAC-signed agentic command channel lets you hook any AI agent as a co-analyst with full read/write map access. AGPL-licensed. https://github.com/BigBodyCobain/Shadowbroker
NVlabs/Sana — 6,082 stars (+450 today). NVIDIA's linear diffusion transformer surging. Efficient high-res image synthesis using a linear transformer — dramatically faster than standard attention. Supports text-to-image and text-to-video. Apache-2.0 licensed. The open-weights image gen space keeps heating up. https://github.com/NVlabs/Sana
K-Dense-AI/scientific-agent-skills — 23,738 stars (+764 today). Week 2: still the deepest vertical skill pack. 135 scientific skills across genomics, drug discovery, materials science, clinical research — now approaching 24K. https://github.com/K-Dense-AI/scientific-agent-skills
Developer Tools
colbymchenry/codegraph — 3,200 stars (+860 today). Day 3: code knowledge graph keeps climbing. Pre-indexed symbol graph for Claude Code — claims 92% fewer tool calls, 71% faster exploration. The "give agents a map instead of a flashlight" pattern is proving popular. https://github.com/colbymchenry/codegraph
calcom/cal.diy — 43,180 stars (+425 today). Cal.com rebrands to cal.diy. The open-source scheduling platform (13.4K forks, 1,371 open issues) is trending again — likely tied to a product rebrand and positioning as "scheduling infrastructure for everyone." T3 stack: Next.js, tRPC, Prisma, Tailwind. https://github.com/calcom/cal.diy
getsentry/junior — 196 stars (+30 today). Early but worth watching: Sentry's AI Slack bot runtime. Hono-powered runtime with plugins for GitHub, Linear, Notion, Datadog, Hex, and Sentry itself. Includes a browser automation plugin. Early-stage (tag: non-production) but from a team that ships. https://github.com/getsentry/junior
HKUDS/CLI-Anything — 35,478 stars (+306 today). "Make all software agent-native" via CLI wrappers. Continuing to grow steadily — the CLI-as-agent-interface pattern has legs. https://github.com/HKUDS/CLI-Anything
Hidden Gems
Andyyyy64/whichllm — 998 stars (+230 today). Brilliant: finds the best local LLM for YOUR hardware. Not "what fits" — what actually performs best. Merges real benchmarks (LiveBench, Chatbot Arena ELO, Aider) with VRAM/bandwidth modeling. Recency-aware scoring so a 2024 model can't outrank a 2026 one on stale benchmarks.
pip install whichllm && whichllm --gpu "RTX 4090"— instant ranked recommendations. The kind of tool everyone running local models needs. https://github.com/Andyyyy64/whichllmdograh-hq/dograh — 1,556 stars (+236 today). Open-source Vapi/Retell alternative. Self-hostable voice agent platform with drag-and-drop workflow builder, WebRTC, and BYO-everything (LLM, TTS, STT). BSD-2 licensed, maintained by YC alumni. While Vapi charges per-minute, Dograh is free to self-host. The voice agent space is getting its "Cal.com moment." https://github.com/dograh-hq/dograh
golemcloud/golem — 1,544 stars (+136 today). Agent-native platform on WebAssembly. Build agents in Rust, TypeScript, Scala, or MoonBit that run as WASM components with durable execution — never lose state, never duplicate work. 136 open issues signal active development. The WASM-as-agent-runtime thesis is intriguing. https://github.com/golemcloud/golem
Notable Trends
The skill registry wars are here. Three tiers: Anthropic's official repo (136K stars), mattpocock/obra ecosystem (89K+195K), and now tech-leads-club entering with a security-first angle. The "13% of skills have vulnerabilities" stat will push the ecosystem toward verified registries fast. This is the npm/PyPI trust problem all over again — but for agent capabilities.
Agents are colonizing non-AI domains. Shadowbroker (OSINT), cal.diy (scheduling), Sentry Junior (ops) — the pattern is the same: take an established domain, add an agent command channel, watch it trend. The question isn't "what will agents do" anymore — it's "what won't they touch."
