[Testing] Show HN: A tool to benchmark LLM APIs (OpenAI, Claude, local/self-hosted) I recently built a small open-source tool to benchmark different LLM API endpoints — including OpenAI, Claude, and self-hosted models (like llama.cpp).<p>It runs a configurable number of test requests and reports two key metrics: • First-token latency (ms): How long it takes for the first token to appear • Output speed (tokens&#x2F;sec): Overall output fluency<p>Demo: <a href="https:&#x2F;&#x2F;llmapitest.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;llmapitest.com&#x2F;</a> Code: <a href="https:&#x2F;&#x2F;github.com&#x2F;qjr87&#x2F;llm-api-test">https:&#x2F;&#x2F;github.com&#x2F;qjr87&#x2F;llm-api-test</a><p>The goal is to provide a simple, visual, and reproducible way to evaluate performance across different LLM providers, including the growing number of third-party “proxy” or “cheap LLM API” services.<p>It supports: • OpenAI-compatible APIs (official + proxies) • Claude (via Anthropic) • Local endpoints (custom&#x2F;self-hosted)<p>You can also self-host it with docker-compose. Config is clean, adding a new provider only requires a simple plugin-style addition.<p>Would love feedback, PRs, or even test reports from APIs you’re using. Especially interested in how some lesser-known services compare.

[API/SDK] Show HN: SmartStepper – Multi-Step Form Library with Config-Based Flow I just released SmartStepper v2 – a declarative and config-based way to handle multi-step forms in React.<p>It lets you define orchestration (next, previous steps), validation, and views via a single config object. No more if&#x2F;else spaghetti or scattered state.<p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;Miladxsar23&#x2F;smartstepper">https:&#x2F;&#x2F;github.com&#x2F;Miladxsar23&#x2F;smartstepper</a> Demo: <a href="https:&#x2F;&#x2F;smartstepper-demo.vercel.app" rel="nofollow">https:&#x2F;&#x2F;smartstepper-demo.vercel.app</a> Docs: <a href="https:&#x2F;&#x2F;github.com&#x2F;Miladxsar23&#x2F;smartstepper#readme">https:&#x2F;&#x2F;github.com&#x2F;Miladxsar23&#x2F;smartstepper#readme</a><p>Would love feedback, suggestions, or examples if anyone tries it!

Show HN: Octelium – FOSS Alternative to Teleport, Cloudflare, Tailscale, Ngrok I have been working on Octelium for quite a few years now but it was open sourced only by late May 2025. Octelium, as described more in detail in the repo&#x27;s README, is simply an open source, self-hosted, unified platform for zero trust resource access that is primarily meant to be a modern alternative to corporate VPNs and remote access tools. It can operate as a remote access&#x2F;corporate VPN (i.e. alternative to Twingate, Tailscale, OpenVPN Access Server, etc...), a ZTNA&#x2F;BeyondCorp platform (i.e. alterntive to Cloudflare Access, Teleport, Google BeyondCorp, etc...), and it can also operate as an API&#x2F;AI gateway, an infrastructure for MCP and A2A architectures and meshes, an ngrok alternative, a homelab infrastructure or even as a more advanced Kubernetes ingress. It&#x27;s basically designed to operate like a unified Kubernetes-like scalable architecture for zero trust secure&#x2F;remote access that&#x27;s suitable for different human-to-workload and workload-to-workload environments. You can read more in detail the full set of main features and links about how it works in the repo&#x27;s README or directly in the docs <a href="https:&#x2F;&#x2F;octelium.com&#x2F;docs" rel="nofollow">https:&#x2F;&#x2F;octelium.com&#x2F;docs</a>

[Code Quality] Show HN: Query your Rust codebase and generate types for anything Hello HN!<p>As a long-time professional Rust developer. I&#x27;ve always been frustrated by the difficulty and &quot;hackiness&quot; of producing bindings to other languages, whether a frontend, an FFI library, etc.<p>Not just in Rust but in any language.<p>After many years of trying existing solutions and trying to make my own, I&#x27;ve finally developed a solution I&#x27;m very happy with.<p>RTK (aka Rust Type Kit) allows you to write Lua scripts that perform queries on your code, such as method calls to Axum&#x27;s `.route`, function definitions, and more, and then receive rich type information including all argument types, function paths, proc macro attributes, and more.<p>Your Lua script can then read this information and emit an output file in any language of your choosing. Or, you can emit compiler errors and use it as a linter of sorts. You can even directly re-emit Rust code itself and use this as a richer proc macro solution!<p>The code example is a bit verbose, so I encourage you to take a look at the repo&#x27;s README. I look forward to hearing your thoughts, or any usecases you may come up with!
