[Other] Show HN: LunaRoute – a high-performance local proxy for AI coding assistants LunaRoute is a high-performance local proxy for AI coding assistants like Claude Code, OpenAI Codex CLI, and OpenCode. Get complete visibility into every LLM interaction with zero-overhead passthrough, comprehensive session recording, and powerful debugging capabilities.<p>- See Everything Your AI Does - get full logs (JSONL), summary of sessions including tokens used (input&#x2F;output) as well as tools usage and success rates.<p>- Privacy &amp; Compliance Built-In - redact or tokenize any sensitive information (regex based).<p>- Speaks OpenAI and Anthropic dialects so you can route (and translate) when needed between models and providers.<p>- High performance - passthrough is 0.1ms - 0.2ms latency. Logging and summary is off loaded to a secondary thread to allow maximum performance.<p>Feedback is always appreciated as well as stars on the repo :)

[Database] Show HN: GoSMig – minimal, type-safe SQL migrations written in Go I built GoSMig for my own projects and open-sourced it in case it helps others. It’s a tiny generic library (no external deps except golang.org&#x2F;x&#x2F;term) for writing SQL migrations in Go with compile-time checks.<p>It supports transactional and non-transactional migrations, rollback, status, version, and a small CLI handler so you can ship your own migration binary.<p>Why another migrator?<p>- Minimal API, no DSL or file layout to learn<p>- Type-safe via Go generics<p>- Works with database&#x2F;sql and sqlx out of the box<p>- Should work with any db library (or wrapper) that implements some generic interfaces (see the &quot;Core Types&quot; section here <a href="https:&#x2F;&#x2F;github.com&#x2F;padurean&#x2F;gosmig?tab=readme-ov-file#core-types" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;padurean&#x2F;gosmig?tab=readme-ov-file#core-t...</a>)<p>- Tested with PostgreSQL, should work with any SQL RDBMS (MySQL, SQLite, MS SQL Server, ...)<p>Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;padurean&#x2F;gosmig" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;padurean&#x2F;gosmig</a><p>Docs &amp; examples: README + examples branch <a href="https:&#x2F;&#x2F;github.com&#x2F;padurean&#x2F;gosmig&#x2F;tree&#x2F;examples" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;padurean&#x2F;gosmig&#x2F;tree&#x2F;examples</a><p>Would love feedback: ergonomics, missing guardrails, API rough edges, and real-world gotchas, etc.

[Other] Show HN: ExprTk REPL – Explore math expressions in the browser with WebAssembly ExprTk compiled to WebAssembly lets you explore and evaluate math expressions instantly in your browser. Everything runs client-side at near-native speed.

[Other] Build your own database

[CLI Tool] Show HN: Clink – Bring your own CLI Agents, Ship instantly Clink lets you use the coding agents you already pay for (Claude Code, Codex CLI, Gemini CLI, Z.ai GLM) to build → live-preview → ship apps in an isolated container.<p>No token purchases, no extra cost for coding. Just link your existing Claude&#x2F;OpenAI&#x2F;Gemini account and start building and deploying instantly.<p>Why we built this:<p>Claude Code is our go-to for coding, but it lacked preview + deploy capabilities. We didn&#x27;t want to pay Lovable again just for that.<p>Different agents excel at different tasks - Claude Code for versatility, Codex for complex work, GLM for speed. We needed one platform to leverage them all.<p>CLI agents offer more freedom than traditional web builders. We wanted to unlock their full potential with proper dev tooling.<p>What it does:<p>• Prompt → Build → Live → Deploy - The fastest path from idea to live website. Deploy for free.<p>• BYO Subscription - Use your existing plans efficiently (Claude Code $20 = 10x Lovable $25 usage, GLM $3 = 3x Claude Code $20)<p>DEV Mode (Beta):<p>• Multi-stack support - Build with Node, Python, Go, Rust and deploy containers to public URLs instantly<p>• Repo imports - Upgrade and deploy your existing projects across any stack<p>Links:<p>• Clink: <a href="https:&#x2F;&#x2F;clink.new" rel="nofollow">https:&#x2F;&#x2F;clink.new</a><p>• OSS origin (Claudable, ~2.8k): <a href="https:&#x2F;&#x2F;github.com&#x2F;opactorai&#x2F;Claudable" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;opactorai&#x2F;Claudable</a><p>We&#x27;d love any feedback, bug reports, or stack requests - we iterate fast and read every comment.

[Other] Show HN: Django Keel – 10 Years of Django Best Practices in One Template After a decade of shipping Django to production, I got tired of solving the same setup problems on every new project.<p>Environment-first settings. Sensible auth defaults. Structured logging. CI from day zero. Pre-commit hooks. Docker. Security hardening. Every project meant two days of boilerplate before writing business logic.<p>So I built Django Keel: a production-ready Django starter that eliminates the yak-shaving. GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;CuriousLearner&#x2F;django-keel" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;CuriousLearner&#x2F;django-keel</a><p>*What you get*:<p>- 12-factor config with environment-based secrets - Production-hardened security defaults - Pre-wired linting, formatting, testing, pre-commit hooks - CI workflow ready to go - Clear project structure that scales - Documentation with real trade-offs explained<p>*Background*:<p>I maintained a popular cookiecutter template for years. Django Keel is what that should&#x27;ve been from the start—battle-tested patterns without the accumulated cruft.<p>*Who it&#x27;s for*:<p>Teams and solo builders shipping Django to production who want a strong baseline without tech debt. Feedback welcome on what works, what doesn&#x27;t, and what&#x27;s missing. Issues and PRs appreciated.
