Free DeepSeek without sign-ups: the trick nobody told you about

There's a GitHub project doing something deceptively simple yet brilliant: it takes DeepSeek's free Web Chat and transforms it into a local API that speaks OpenAI and Anthropic's language. Result? You use DeepSeek like it's ChatGPT, zero registration required, zero dollars spent.

Why does it matter? Because you can now plug DeepSeek into any tool that accepts standard APIs—your own custom app, Open WebUI (the open-source ChatGPT alternative), or Python scripts grinding away 24/7. The proxy sits invisibly between your code and DeepSeek's servers, handling all the messy translation behind the curtain.

Here's where it gets even spicier: it supports streaming (watch responses appear line by line instead of waiting for the whole thing), tool calling (let the AI use external tools like calculators or APIs), and even the Responses API—basically every feature a "real" paid service would charge for. It's like getting enterprise-grade AI access for absolutely nothing.

Who wins? First, anyone wanting to experiment with powerful AI without a credit card—students, hackers, indie devs. Second, people who care about continuity: a local API means no external downtime, no surprise throttling, no sudden ToS curveballs. It's a proxy that doesn't expire.

The setup? Not exactly drag-and-drop if you don't speak terminal, but nowhere near rocket science either. You clone the repo, install Python dependencies, fire up the proxy, and suddenly your machine becomes a gateway between your apps and DeepSeek. To the outside world, nothing changes; the app using it thinks it's talking to OpenAI.

One caveat: technically you're bypassing the web chat's request limits, so it lives in that gray area of ToS interpretation. DeepSeek probably won't care (for now), but if they get aggressive, blocks could happen. It's the risk of any free workaround—though the project itself is clean enough not to cause much fuss.
