CodeRouter

What it does

Claude Code and Cursor route everything through Opus ($75/M tokens) — even file reads and commit messages. CodeRouter adds phase-aware task routing: it detects what you're doing and picks the optimal model. Planning gets Opus. Implementation gets Sonnet/DeepSeek. Tests get Flash. Real result: $212/mo to $63/mo. One URL change, same workflow. Works with Cursor, Claude Code, Aider, Copilot, Windsurf. 1M free tokens on signup.

Phase-aware LLM router for AI coding agents. CodeRouter detects whether your request is planning, implementing, debugging, testing or documenting — and routes it to the cheapest capable model (DeepSeek V4 Pro, Kimi, GLM-5.2, Sonnet 4.6, Gemini 3 Pro) instead of paying Opus prices for everything. Works with Cursor, Aider, Claude Code, Copilot, Windsurf, Continue.dev, OpenClaw and any OpenAI-compati

Your agent sends planning calls, implementation calls, debugging calls, small edits . CodeRouter detects each phase and routes to the cheapest model that still matches Claude's quality — typical 70–90% savings vs direct Anthropic . Savings estimates are based on typical mixed coding workloads where phase-aware routing sends most requests to lower-cost models instead of a single premium model. Actual savings vary by usage mix, model selection, and cache hit rate. Same OpenAI-compatible API. But instead of making you pick a model manually for every request, CodeRouter detects what phase of coding your agent is in — planning, implementation, debugging, test generation — and picks the cheapest…from coderouter.io

  Smart model routing directly in Claude, Codex and CursorJun 2026 · github.com · ▲216

  We built a model router that plugs into coding agents (e.g. Claude Code, Codex, Cursor, etc.) and intelligently sends requests to the best model to serve them. Here's a quick demo of running it locally: https://www.youtube.com/watch?v=isKhAyivtfM. At Weave, we write most of our code with AI, and it's been getting more expensive. This came to a head when Opus 4.7 was released and, thanks to its tokenizer changes, our costs shot up. We knew we didn't need Opus for everything but we didn't want to lose out on the intelligence for the cases where you really need it. So we decided…

  Skill that lets Claude Code/Codex spin up VMs and GPUsFeb 2026 · cloudrouter.dev · ▲138

  I've been working on CloudRouter, a skill + CLI that gives coding agents like Claude Code and Codex the ability to start cloud VMs and GPUs. When an agent writes code, it usually needs to start a dev server, run tests, open a browser to verify its work. Today that all happens on your local machine. This works fine for a single task, but the agent is sharing your computer: your ports, RAM, screen. If you run multiple agents in parallel, it gets a bit chaotic. Docker helps with isolation, but it still uses your machine's resources, and doesn't give the agent a browser, a desktop, or a GPU to…

  CodeBurn – Analyze Claude Code token usage by taskApr 2026 · github.com · ▲112

  Built this after realizing I was spending ~$1400/week on Claude Code with almost no visibility into what was actually consuming tokens. Tools like ccusage give a cost breakdown per model and per day, but I wanted to understand usage at the task level. CodeBurn reads the JSONL session transcripts that Claude Code stores locally (~/.claude/projects/) and classifies each turn into 13 categories based on tool usage patterns (no LLM calls involved). One surprising result: about 56% of my spend was on conversation turns with no tool usage. Actual coding (edits/writes) was…

  Playwright Skill for Claude Code – Less context than playwright-MCP2025 · github.com · ▲189

  I got tired of playwright-mcp eating through Claude's 200K token limit, so I built this using the new Claude Skills system. Built it with Claude Code itself. Instead of sending accessibility tree snapshots on every action, Claude just writes Playwright code and runs it. You get back screenshots and console output. That's it. 314 lines of instructions vs a persistent MCP server. Full API docs only load if Claude needs them. Same browser automation, way less overhead. Works as a Claude Code plugin or manual install. Token limit issue:…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
