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.
Developer Tools
Kuri
Zig-powered browser tool for AI agents: 464KB binary, 3ms cold start, zero Node.js

Kuri is a browser automation tool written in Zig, designed specifically for AI agent workloads. The entire binary weighs 464KB with a cold start of approximately 3ms — a stark contrast to Playwright or Puppeteer, which drag in hundreds of megabytes of Node.js runtime and dependencies. Kuri ships 40+ HTTP API endpoints and bundles four capabilities in one: a Chrome DevTools Protocol (CDP) server, a standalone page fetcher, a terminal browser, and an agentic CLI. The key engineering insight is that AI agents spend a lot of their latency budget waiting for browser tooling to spin up. By rebuilding the whole stack in Zig, Kuri eliminates that cost. It also includes built-in anti-detection stealth layers — useful when agents need to scrape or interact with sites that gate on bot signals. The team claims a 16% reduction in tokens-per-workflow cycle compared to Playwright-based setups, which has real cost implications at scale. Early community reception on Hacker News was positive, with developers noting the Zig choice as a credible engineering decision rather than a language hipster move. With 119 GitHub stars within hours of posting, the project is clearly scratching a real itch for the growing population of agent developers who treat browser automation as table stakes but hate paying Playwright's overhead tax.
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.”
“Finally — browser automation that doesn't require npm install to bring in 300MB of Node.js just to click a button. The 3ms cold start is genuinely game-changing for agent loops where you're spinning up browser contexts dozens of times per session. If the anti-detection stealth holds up, this becomes my go-to for agentic scraping pipelines.”
“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.”
“Zig is a great systems language but its ecosystem is tiny — debugging weird browser edge cases without a mature community is going to be painful. Playwright has years of battle-testing across millions of CI pipelines; 119 stars and a fresh repo don't. Wait until the CDP compatibility gaps are documented and at least a few production deployments are public.”
“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 shift toward agent-native infrastructure is accelerating — and browser tooling is a huge bottleneck. Kuri represents the first wave of tools being built from scratch for agents, not adapted from human-centric automation. The 16% token reduction compounds dramatically at the workflow orchestration layer. This is early infrastructure for the agentic web.”
“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.”
“For creator workflows that involve research agents scraping dozens of pages, the speed difference is immediately felt. Less time waiting for browsers to initialize means faster content pipelines. The zero-dependency binary is also great for shipping as part of a creator tool suite without Node version nightmares.”
