What it does
Your AI agent shouldn't chain you to a terminal. Backgrind floats it in an always-on-top window over any app — even a fullscreen game — and pings you only when it actually needs a decision. Bring your own (Claude Code, Cursor) or use Grindy, the built-in agent with zero setup. Multi-agent tabs, voice, Build/Plan, click-through, local-first — your login, your history.
Run your AI coding agent — Claude Code, Cursor, Codex — in an always-on-top overlay window that pings you only when it needs you. macOS & Windows.
Claude Code, Cursor, Codex, or our hosted Grindy — floating over whatever you're in, pinging you only when an agent actually needs you. Fade the overlay out and get back to reading, browsing, or gaming. When an agent needs a yes/no — or has a question — a small card slides in, you tap it, and everything keeps grinding. Every 'Always allow' becomes a rule — scoped to the repo and command, with a hit counter and a full audit trail. The overlay interrupts you less every single day, and never silently widens what it may do. Ask your own Claude, Codex, and Gemini the same hard question. Backgrind runs them in parallel inside your repo, then a chairman model weighs consensus, contradictions, and…from backgrind.com

Spotlight by BackplanesJun 2026 · backplanes.com · ▲394Hola HN! Long time lurker, sometimes commentor, first time poster here. I’ve been working alongside my two co-founders and a few colleagues on a project I’m excited (and a little nervous) to share with you all! Like many of us, I’ve lived a tortured existence with AI coding (is it vibes?) over the past few months - I think November was a big moment with this. But, one thing I’ve noticed after building orchestration layer after orchestration layer is that the thing I always came back to was “what the hell is Claude Code actually doing?” Perhaps it’s because of the time Claude Code got…

ViberiaMay 2026 · getviberia.com · ▲146Hey HN, This is my take on the agent harness. Everything on an isometric map. Agents are grouped into "buildings" that run in a sequence or a loop; e.g., the CodeForge has an agent that writes a PRD, another one that implements, and a third that reviews. Everything is customizable, you build your own buildings/teams however you want. It's a Tauri app, really light (about 8x less energy than the closest competitor I benchmarked, so it actually runs from a coffee shop on battery). It's macOS only for now, but ping me if you are willing to test the Windows or Linux version. I've been…
- AAAI agents play SimCity through a REST APIFeb 2026 · hallucinatingsplines.com · ▲216
This is a weekend project that spiraled out of control. I was originally trying to get Claude to play a ROM of the SNES SimCity. I struggled with it and that led me to Micropolis (the open-sourced SimCity engine) and was able to get it to work by bolting on an API. The weekend hack turned into a headless city simulation platform where anyone can get an API key (no signup) and have their AI agent play mayor. The simulation runs the real Micropolis engine inside Cloudflare Durable Objects, one per city. Every city is public and browsable on the site. LLMs are awful at the spatial stuff, which…
AgentGridJul 2026 · agentgrid.sh · ▲77Hi HN, I’m Michael, I built AgentGrid with my friend Souren because we were tired of losing our coding sessions and couldn't keep track of what was actually being built across our many projects. Our approach was to use an infinite canvas desktop app for the TUIs we already know and love, mainly claude + codex. We drew inspiration from Figma and Railway. Overtime we added image nodes, notes, terminals, coding editors, source control, etc. I wasn't sure about it at first. It took me a month to give the first version Souren built a real try. What got me was an Apple System Update I've been…
TaskShellApr 2026 · taskshell.app · ▲86I initially built this for myself but some folks asked me to open access to it. Let me explain what I built and why. I'm a product designer who transitioned from only designing to building complete software products myself and I found myself using AI coding agents literally every day. I started with cursor, then codex and claude code, then kilo code, and then moved to opencode. The only thing AI agents couldn't get done for me was to keep track of my todos and tasks for all my projects. I ended up vibe coding a todo app separately or using apps like TickTick. The main issue with separate…

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
