ds2api is a Go middleware that wraps DeepSeek's web chat interface and re-exposes it as fully compatible OpenAI, Claude, and Gemini API endpoints. Developers can point any existing SDK or tool that speaks these protocols at a local ds2api instance and get DeepSeek responses without rewriting a line of integration code. It handles multi-account pooling, per-account rate limiting, proof-of-work computation (which DeepSeek's web layer requires), and context management for long conversations. The architecture is surprisingly complete for a solo project: a Go backend for concurrency and protocol translation, a React management dashboard, Docker/Vercel deployment support, and compiled binaries for Linux, macOS, and Windows. It even adapts tool-calling semantics across different provider formats — a notoriously tricky edge case. The project has attracted nearly 3,000 GitHub stars and 461 in a single day, suggesting real demand for free or cheap DeepSeek access routed through familiar APIs. The catch: DeepSeek's ToS doesn't allow automated web scraping, and the README explicitly limits use to "learning and internal verification." That said, the technical execution is impressive and the architecture is worth studying regardless.

smolvm
Sub-200ms microVMs for sandboxing AI coding agents safely

smolvm is a lightweight microVM runtime built in Rust on top of libkrun, designed specifically for sandboxing AI coding agents and untrusted code execution. VMs cold-start in under 200ms and ship as portable `.smolmachine` files — think Docker images but hardware-isolated. It supports macOS (Apple Silicon and Intel) and Linux, with opt-in networking so that untrusted code can't exfiltrate credentials or phone home by default. The project includes an explicit AGENTS.md to help coding agents understand how to use it, and was built with autonomous code execution in mind. When an AI agent needs to run user-submitted code or iterate on its own suggestions, smolvm gives it a proper hardware sandbox rather than a leaky container. Version v0.5.18 landed April 17, 2026. With AI coding agents increasingly running arbitrary code in tight loops, the security story around containerization has become critical. smolvm fills a real gap: fast enough to not break agentic workflows, isolated enough to actually protect the host machine and credentials. It surfaced on Hacker News with 259 points and strong technical discussion, suggesting genuine resonance with the developer community building agentic tools.
Reviewer scorecard
“If you have a DeepSeek account and want to use it through your existing OpenAI-compatible stack, this is the cleanest solution I've seen. The multi-account pooling and automatic rate-limit handling are genuinely thoughtful engineering.”
“This is the missing layer for anyone running AI agents that execute code. Docker containers have always been too porous for untrusted execution, and smolvm's sub-200ms coldstart means you can spin a fresh VM per agent turn without killing your latency budget. The AGENTS.md is a thoughtful touch — shows the authors actually understand the workflow.”
“This is web scraping dressed up as an API — and DeepSeek's ToS explicitly forbids it. You're one UI update away from your middleware breaking entirely. For production use, just pay for the official API; it's already cheap.”
“At v0.5.18 this is still early software and the docs are sparse. libkrun has its own surface area of bugs, and running microVMs at agent-loop speed on macOS introduces a whole class of Apple Hypervisor Framework edge cases. I'd wait for v1.0 and a production case study before betting real workloads on this.”
“This pattern — wrapping web interfaces as protocol-compatible APIs — is going to proliferate as AI providers fragment. ds2api is an early proof-of-concept for a class of tools that lets developers treat the web as an API surface.”
“Every autonomous agent that executes code needs a proper sandbox — not a polite request for the agent to be careful. smolvm represents the infrastructure layer that makes truly autonomous code execution safe enough to deploy at scale. This kind of primitive is foundational for the agentic software era.”
“As someone who builds content pipelines, the ToS uncertainty makes this a hard pass for anything customer-facing. The Go architecture is slick but the legal exposure isn't worth it for a production tool.”
“For anyone building AI tools that touch code, smolvm means you can let your AI actually run things without fear. That unlocks a whole category of 'show me the output' UX patterns that weren't safe before. Less time explaining sandboxing to users, more time shipping features.”
