[CLI Tool] Show HN: Gotui – a modern Go terminal dashboard library I’ve been working on gotui, a modern fork of the unmaintained termui, rebuilt on top of tcell for TrueColor, mouse support, and proper resize handling. It keeps the simple termui-style API, but adds a bunch of new widgets (charts, gauges, world map, etc.), nicer visuals (collapsed borders, rounded corners), and input components for building real dashboards and tools. Under the hood the renderer’s been reworked for much better performance, and I’d love feedback on what’s missing for you to use it in production.

[Other] Show HN: I built a WebMIDI sequencer to control my hardware synths Hey HN,<p>I’m an ex-Google engineer trying to get back into music production.<p>I needed a way to sequence my hardware synths using AI contexts without constantly switching windows, so I built this.<p>It runs entirely in the browser using WebMIDI. No login required. It connects to your local MIDI devices (if you&#x27;re on Chrome&#x2F;Edge) and lets you generate patterns.<p>Tech stack: [React &#x2F; WebMIDI API &#x2F; etc].<p>Link: www.simplychris.ai&#x2F;droplets<p>Code is a bit messy, but it works. Feedback welcome.

[CLI Tool] Show HN: Chess-TUI Play Lichess games in your terminal (Rust) Hi HN, I’ve released a new version of chess-tui, a Rust terminal UI for playing live games against Lichess opponents.<p>The update includes a cleaner TUI, better performance, improved keybindings, and smoother real-time integration with the Lichess API. It’s designed as a simple, fast way to play chess without leaving the terminal.<p>Repo:<a href="https:&#x2F;&#x2F;github.com&#x2F;thomas-mauran&#x2F;chess-tui" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;thomas-mauran&#x2F;chess-tui</a><p>Feedback and bug reports are welcome. Happy to answer questions!

[DevOps] Ship AI Agents to Google Cloud in minutes, not months. Production-ready templates with built-in CI/CD, evaluation, and observability.

[DevOps] Show HN: Titan – JavaScript-first framework that compiles into a Rust server Hi HN,<p>I built Titan, a backend framework where you write routes and logic in JavaScript, and the CLI compiles everything into a single Rust + Axum binary using the Boa JS engine. No Node.js is required in production.<p>The idea is to keep JS developer experience while getting Rust performance and a self-contained deployable server.<p>Current features:<p>JS route DSL<p>Action system mapped to Rust<p>esbuild bundling<p>Generated Rust server with Axum<p>Hot-reload dev server<p>Single-binary output<p>Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;ezet-galaxy&#x2F;-ezetgalaxy-titan" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;ezet-galaxy&#x2F;-ezetgalaxy-titan</a><p>Would love feedback on the architecture, DX, and whether this hybrid JS→Rust approach is useful.<p>Thanks for reading!

[API/SDK] A modern data client for React & tRPC fate is a modern data client for React and tRPC inspired by Relay and GraphQL. It combines view composition, normalized caching, data masking, Async React features, and tRPC's type safety. fate is designed to make data fetching and state management in React applications more composable, declarative, and predictable. The framework has a minimal API, no DSL, and no magic—it's just JavaScript.

[Other] Show HN: Cupcake – Better performance and security for coding agents (via OPA) We&#x27;re releasing early efforts on coding agent governance with Cupcake [1] - an open-source policy enforcement layer with native integrations. You write rules in policy-as-code (OPA&#x2F;Rego), and Cupcake integrates them into the agent runtime via Hooks.<p>See it in action (Desktop only): <a href="https:&#x2F;&#x2F;cupcake-policy-studio.vercel.app&#x2F;example-policies&#x2F;security&#x2F;protecting-paths?harness=claude-code&amp;format=rego" rel="nofollow">https:&#x2F;&#x2F;cupcake-policy-studio.vercel.app&#x2F;example-policies&#x2F;se...</a><p>Help us build: <a href="https:&#x2F;&#x2F;github.com&#x2F;eqtylab&#x2F;cupcake" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;eqtylab&#x2F;cupcake</a><p>We are EQTY Lab, our mission is verifiable AI (identity, provenance, and governance). With the rise of capable agents like Claude Code, it became immediately clear that those deploying these agents need the ability to conduct their own alignment and safety controls. We can’t rely solely on the frontier labs.<p>This is why we created the feature request for Hooks in Claude Code [2], and pivoted away from filesystem and OS-level monitoring once those hooks were implemented. Hooks provide the critical points we need:<p>* Evaluation: Checking agent intent and actions.<p>* Prevention: Stopping unsafe or unwanted actions.<p>* Modification: Adjusting the agent&#x27;s output before execution.<p>Policy-as-Code with OPA&#x2F;Rego - While many agent security papers suggest similar policy architectures using invented DSLs, Cupcake is fundamentally built on Open Policy Agent (OPA) and its policy language, Rego [3].<p>We chose Rego because it is:<p>* Industry-Robust: Widely adopted across enterprise DevSecOps and cloud-native environments.<p>* Purpose-Built: Offers unique, mature advantages for defining, managing, and enforcing policy as code.<p>* Enterprise-Oriented: This makes Cupcake compatible with existing enterprise governance frameworks.<p>Cupcake is released under the Apache-2.0 license. We will formalize a path to v1.0.0 in Q1 of 2026. This is an early preview version. The goal with Cupcake is not suppression, but to ensure an agent is able to drive fast without crashing.

[Other] Show HN: Wirebrowser – A JavaScript debugger with breakpoint-driven heap search Hi HN!<p>I&#x27;m building a JavaScript debugger called Wirebrowser. It combines network inspection, request rewriting, heap snapshots, and live object search.<p>The main experimental feature is BDHS (Breakpoint-Driven Heap Search): it hooks into the JavaScript debugger and automatically captures a heap snapshot at every pause and performs a targeted search for the value or structure of interest. This reveals the moment a value appears in memory and the user-land function responsible for creating it.<p>Another interesting feature is the Live Object Search: it inspects runtime objects (not just snapshots), supports regex and object similarity, and lets you patch objects directly at runtime.<p>Whitepaper: <a href="https:&#x2F;&#x2F;fcavallarin.github.io&#x2F;wirebrowser&#x2F;BDHS-Origin-Trace" rel="nofollow">https:&#x2F;&#x2F;fcavallarin.github.io&#x2F;wirebrowser&#x2F;BDHS-Origin-Trace</a><p>Feedback very welcome, especially on whether BDHS would help your debugging workflow.
