free-claude-code is a lightweight proxy that intercepts Claude Code's Anthropic Messages API calls and reroutes them to six alternative backends: NVIDIA NIM, OpenRouter, DeepSeek, LM Studio, llama.cpp, and Ollama. From Claude Code's perspective nothing changes — the UX, tool calls, streaming, and reasoning blocks all work identically. Under the hood, you're spending almost nothing. The project supports per-model routing, so you can send Opus traffic to OpenRouter while Haiku goes to a local Ollama instance. It handles the full protocol stack: streaming completions, multi-turn tool use, thinking block pass-through, and request optimization for local hardware. An optional Discord or Telegram bot wrapper lets you trigger remote coding sessions from your phone. With 17K+ GitHub stars and still climbing, this is clearly scratching a real itch. The Anthropic gating of Claude Code behind Pro subscriptions created exactly the market condition this project was built for. Whether it stays ahead of API changes is the open question — but right now it's the fastest path to a near-free Claude Code experience.

Mercury Coder Next Edit
Sub-100ms next-edit prediction for VS Code and JetBrains — powered by diffusion LLMs

Inception Labs launched Next Edit inside the Continue extension, bringing Mercury Coder's diffusion-based architecture to VS Code and JetBrains. Unlike autoregressive autocomplete that generates left-to-right, Mercury predicts multi-line edits across your entire file simultaneously — deletions, additions, and structural changes at once. Common patterns it handles: converting callbacks to async/await, extracting functions, renaming variables across call sites, and squashing code smells. Latency is under 100ms so suggestions appear before you finish thinking. The diffusion architecture ($0.25/M input, $1/M output) is 5-10x faster than comparable autoregressive models. Available via Models Add-On in Continue.
Reviewer scorecard
“This is exactly what the indie dev community needed after Anthropic tightened Pro limits. The per-model routing is clever — I can push heavy reasoning to DeepSeek and let fast autocomplete hit a local 8B model. Setup took about 15 minutes.”
“I've used next-edit features in other tools but the sub-100ms latency here is genuinely different — it's below my perception threshold, which means it doesn't break flow. The multi-line simultaneous edit understanding is real; it caught a refactor pattern I was about to manually do across 6 call sites.”
“This is a proxy built around undocumented client behavior — any Claude Code update could break it silently. Running your codebase through third-party provider APIs also introduces real IP and data risk. For solo projects it's probably fine; for anything professional, think twice.”
“The benchmarks are impressive but 'trained on real edit sequences' is doing a lot of work here. Until I see how it handles domain-specific refactors in large codebases with complex type hierarchies, I'm skeptical it beats Cursor's native next-edit on anything beyond textbook patterns.”
“The fact that 17K people starred this in days is a signal: developers want Claude Code's UX without the lock-in. This kind of proxy layer is how model pluralism actually happens in practice — not through official integrations but through community shims.”
“Diffusion LLMs applied to code editing is the most underrated architectural bet in AI tooling right now. Autoregressive generation was always the wrong primitive for editing — you don't write a diff token by token. Mercury's approach is structurally correct and the speed numbers suggest it scales without compromise.”
“If you're not deep in CLI-land, the setup friction is real. But for technical creators who've been priced out of Claude Code Pro, this is a legitimate workaround while the pricing landscape settles.”
“Even for non-heavy-coders, the 'fix code smells' and 'rename across call sites' use cases are exactly the tedious tasks that make coding feel like work instead of creation. Sub-100ms means zero cognitive interrupt. This is the kind of AI assist that disappears into the background in a good way.”
