Hey — Guy here.

Two weeks ago Microsoft killed Claude Code internally. Last week Google bet all of I/O on agents. This week the most interesting thing in AI coding didn't come from any of the giants — it came from a GitHub repo with 165,000 stars and no marketing budget. Open source is quietly eating the terminal while everyone watches the trillion-dollar players trade blows.

🧠 This Week in AI Coding

• OpenCode crossed ~165,000 GitHub stars — and is now openly called "the de facto open-source Claude Code." Provider-agnostic, runs local models via Ollama, polished terminal UI, 7.5M+ monthly devs. Built by a tiny team (the terminal.shop folks), not a lab. The lesson: you don't need a frontier model to win the harness layer.
• OpenWork hit 15.5K stars as an open-source Claude Cowork alternative — a local-first desktop app built on top of OpenCode that lets teams ship repeatable agentic workflows. The proprietary-vs-open race that defined browsers in the 2000s is now happening for agents, on fast-forward.
• Anthropic's "Cowork" keeps expanding — 20+ MCP connectors and 12 practice-area plugins (legal vertical first) shipped open source. Anthropic is betting the connectors are the moat, not the app. Watch this pattern: give away the shell, monetize the model + the integrations.
• Cursor shipped Composer 2.5 — its in-house long-horizon model that now matches Opus 4.7 on benchmarks. Cursor no longer just wraps frontier models; it's building its own. That's a real strategic shift for a company that started as a VS Code fork.
• The market share story is now official: Copilot fell from 67% → 51% among pro devs, Cursor debuted at 18%, Claude Code hit 10% on its first survey appearance. The Microsoft monopoly is genuinely over — three tools within arm's reach of each other.
• GitHub's billing change lands June 1 — Copilot moves to usage-based pricing and paused new Pro/Pro+ sign-ups. The flat-rate era I wrote about a few weeks ago is officially closing across the board.
• Google's Gemini 3.1 Ultra is shipping with a 2M-token context window (native text/image/audio/video) plus Gemini Spark, a general agent in the Gemini app. The context arms race didn't stop — it just moved up an order of magnitude.

🚀 What We Shipped at VeriduxLabs

Building in public, so here's the honest version:

• Opened a permanent mobile-native lane. Turns out we already had five mobile codebases sitting in the portfolio. First three to ship: Zmani (a Hebrew halachic-times calendar — Expo + React Native, Play Store assets ready, launch imminent), then Plate Penalty (food-photo → calorie estimate via Gemini Flash), then a SPARit mobile companion. Sometimes the move isn't building more — it's shipping what's already 80% done.
• VCA makeover handed off to a coding agent. Wrote a full self-contained audit-and-rebuild brief (12 areas, 3-phase ship framework) for Cursor to take Vibe Coding Academy end-to-end. New CURSOR-TASK-* handoff convention — three different AI agents now coordinate through files in one repo.
• First-dollar focus locked. Migrating VCA payments from dormant Paddle → live Lemon Squeezy and activating the course gate. One lever this week; everything else runs on autopilot.
• YouTube: backlog fully cleared on @endofcoding — every rendered video is now live. Next batch in production.

🛠 Tool of the Week: OpenCode

If you've been Claude-Code-curious but allergic to vendor lock-in, this is your week. OpenCode is a free, MIT-licensed, terminal-native coding agent that talks to 75+ model providers — Anthropic, OpenAI, Google, or a fully local model through Ollama. Same agentic loop (read files, run commands, edit code, verify), zero subscription, and you own the whole stack.

Mini-review: the TUI is genuinely good, switching models mid-task is one keystroke, and running it against a local model on a beefy laptop means you can code agentically on a plane with no API bill. It's not quite as polished as Claude Code on the hardest long-horizon tasks yet — but for 90% of day-to-day work, the gap is smaller than the price difference suggests. Try it: opencode.ai.

🔗 Quick Links

• OpenCode — the open-source agent that hit 165K stars
• OpenWork on GitHub — open-source Claude Cowork alternative
• The New Stack: Cursor, Claude Code & Codex are merging into one stack nobody planned
• Awesome CLI Coding Agents — the full terminal-agent landscape, curated

That's the week. The takeaway I keep coming back to: in 2026, the model is increasingly a commodity and the harness is where the real fight is — and open source just proved it can win the harness without a lab behind it. Worth watching where your tooling loyalty actually sits.

See you next Sunday, Guy
