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.
Reviewer scorecard
“Open-source Retool alternative that you can self-host. JavaScript transformations and API bindings are flexible.”
“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.”
“Self-hostable internal tool builder. For internal dashboards and admin panels, it saves real development time.”
“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.”
“Low-code internal tools are becoming standard. Open-source options like Appsmith democratize access.”
“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.”
“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.”
