Collab.Code

What it does

Collab.Code is a collaborative coding workspace built to make creating together seamless. Instead of switching between multiple tools for coding, communication, and feedback, it brings collaboration into a shared environment. Built for teams, students, and creators, it enables real-time co-creation, faster iteration, and more interactive workflows—turning coding from an isolated task into a connected experience where ideas are built together.

Real-time collaborative coding with live cursors, Y.js CRDTs, AI code review, and sandboxed multi-language execution. A product of PsychFlo.

Real-time CRDT sync. AI review built in. Sandboxed execution. Everything your team needs, nothing it doesn't. Not a toy demo. Every piece is production-grade with a real distributed systems architecture behind it. Y.js vector clocks guarantee every edit converges — no merge conflicts, no locking, no data loss. The same engine powering Figma and Notion. Streaming code review, auto-fix, test generation, and docs — five review modes, results in seconds. Run JS, TypeScript, Python, Go, and Bash in isolated sandboxes. 8s timeout, 50 KB cap — safe, fast, no setup. Built-in countdown timer, problem statement panel, and structured scoring rubric. Everything a technical screen needs. Socket.IO +…from collabcode.psychflo.com

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
