free-claude-code is a Python proxy that intercepts Anthropic API calls from Claude Code CLI, VSCode extensions, and IntelliJ, then routes them to alternative providers — NVIDIA NIM (40 free requests/minute), OpenRouter, DeepSeek, LM Studio, or llama.cpp locally. Change two environment variables and your existing Claude Code setup uses the new backend. The proxy supports per-model routing, letting you send Opus requests to one provider and Haiku to another. It handles thinking token parsing, heuristic tool call parsing for models that output tools as text, and smart rate limiting with proactive throttling. There's also Discord and Telegram bot support for remote autonomous coding sessions. This project exploded to nearly 10,000 GitHub stars in a day, making it the fastest-trending non-HuggingFace repo on the platform right now. The ethical picture is nuanced — it doesn't bypass Anthropic's servers, it routes to legitimately licensed models on other providers. But it deliberately sidesteps Anthropic's revenue model. Worth watching how Anthropic responds, and whether NVIDIA's free NIM tier survives the incoming traffic.

Passmark is an open-source Playwright library that lets you write test steps in natural language instead of code. On first run, an AI executes and interprets each step, caching the results to Redis. Every subsequent run replays cached steps at native Playwright speed — no LLM calls, no latency, no cost. Self-healing selectors automatically re-cache when UI changes break existing tests. The library includes multi-model consensus assertions for complex checks, built-in email testing for OTP and verification flows, and drops into existing CI pipelines without requiring infrastructure changes. The open-source core is MIT-licensed and self-hosted; Bug0 offers a managed service for teams that want zero-ops testing infrastructure. Passmark solves the two biggest problems with AI-powered testing: the ongoing LLM cost per test run, and the brittleness of AI-generated selectors. By caching on first execution and self-healing on breakage, it threads a needle that most similar tools miss.
Reviewer scorecard
“For the 80% of Claude Code usage that's just routine coding tasks, DeepSeek V4 via this proxy is genuinely indistinguishable in quality. I'm saving $200/month and the setup took five minutes. The per-model routing is smart engineering.”
“The Redis caching architecture is the key insight here — you get AI test authoring without paying per-run LLM costs. Self-healing selectors alone would justify the switch from vanilla Playwright. This is the first AI testing tool I've seen that actually solves the economics.”
“Let's be honest about what this is: a tool designed to take the Claude Code UX while cutting Anthropic out of the revenue. The open-source models it routes to are meaningfully worse for complex reasoning tasks, and you're one NVIDIA NIM policy change away from a broken workflow.”
“'Plain English tests' sounds great until you're debugging a flaky test at 2am and there's no code to inspect. Cache invalidation and selector healing introduce new failure modes that are harder to reason about than a broken CSS selector. The $2,500/mo managed tier also targets a narrow customer segment.”
“This is the natural result of building dev tooling on top of proprietary API pricing. It proves the interface is now the moat, not the model. Anthropic should take note: developers will build around cost walls if the cost walls are high enough.”
“Test suites written in natural language are the right long-term architecture for software verification. When tests read like requirements documents and maintain themselves, the feedback loop between product and engineering shortens dramatically. Passmark's caching layer is what makes this scalable today.”
“The setup is too technical for most creatives, and the quality inconsistency across providers would drive me crazy mid-project. I'd rather pay for the real thing and get reliable results.”
“For design system teams, plain English tests that describe UX intent rather than CSS selectors mean tests survive redesigns without constant maintenance. The OTP/email testing support is a practical bonus for auth-heavy product flows.”
