ds2api is a lightweight Go middleware server that acts as a protocol translation layer between AI clients and multiple provider APIs. It accepts requests in any major client format and converts them to the target provider format — covering OpenAI, Anthropic Claude, Google Gemini, and others. Multi-account rotation is built in: you can pool API keys across accounts to spread load and reduce rate-limit exposure. The project is minimal by design — a single Go binary that runs locally or in a container. It's aimed at developers and teams who work with multiple AI providers and want a single endpoint that handles format conversion and key rotation transparently. No vendor lock-in, no cloud dependency. ds2api is gaining traction in the local LLM and API arbitrage communities who run self-hosted models alongside commercial APIs and need a clean routing layer. The multi-account rotation feature is particularly relevant for power users who maintain multiple accounts across providers to work around per-account rate limits — a controversial-but-common practice.

GitNexus
Knowledge graph for any codebase — runs in browser via WASM

GitNexus is a zero-server code intelligence engine that solves one of the core limitations of LLM coding assistants: they rediscover code structure from scratch on every query. Instead, GitNexus precomputes a full knowledge graph of your codebase — every function, dependency, call chain, and execution flow — then exposes it through a Graph RAG agent and native MCP tools for editors like Claude Code, Cursor, and Codex CLI. The architecture is unusual: the entire engine compiles to WebAssembly, meaning it runs both in Node.js and fully client-side in the browser without any server infrastructure. The Graph RAG layer performs multi-hop reasoning over the code graph rather than simple embedding similarity, which means it can answer "what would break if I change this function" rather than just "where is this function defined." MCP tool exposure means AI agents in supporting editors can query the graph natively. The tool gained 837 new GitHub stars today as it caught a second wave of attention after its February launch. It's particularly compelling for monorepos and multi-language projects where file-by-file context injection fails. The PolyForm Noncommercial license makes it free for open-source projects, with commercial licensing available through AkonLabs for teams.
Reviewer scorecard
“Single-binary Go middleware with zero dependencies for multi-provider API routing is exactly what I've been hacking together manually. The key rotation is the killer feature for anyone running high-volume agent workloads against rate-limited APIs.”
“This tackles something I've been hacking around manually — pre-feeding dependency graphs into context windows before big refactors. The Graph RAG approach is genuinely smarter than pure embedding similarity for code questions. The MCP integration means it slots directly into Claude Code without any glue code.”
“Multi-account rotation specifically to evade rate limits sits in murky territory for most providers' terms of service. Using this in production could get accounts banned. The legality question matters before you build your infrastructure on this.”
“Knowledge graphs for code have been tried many times — they age quickly as the codebase evolves and require constant re-indexing to stay accurate. The PolyForm Noncommercial license is ambiguous enough to cause legal anxiety for any commercial team. Wait for a clear SaaS tier with managed indexing before committing.”
“Protocol translation layers are foundational infrastructure for the multi-model world we're heading into. Tools like ds2api are what allow developers to build provider-agnostic systems today, before providers offer official cross-compatibility.”
“The WASM-first architecture is prescient — it means GitNexus can live inside browser-based dev environments like StackBlitz and CodeSandbox without any server costs. As AI coding agents become first-class citizens of IDEs, pre-computed code graphs become the memory layer those agents rely on. This is early infrastructure.”
“For most creators, this adds unnecessary infrastructure complexity. Unless you're burning through rate limits regularly, just use the official SDKs and switch providers manually when needed.”
“I don't write code professionally but I use AI tools to build side projects, and the 'why is this breaking everything' question is my biggest frustration. A tool that maps what depends on what and can answer those questions in plain language would genuinely change how I work with AI assistants.”
