Product Hunt
Shipping fast with AI? Specsight turns code changes into a living product map, feature knowledge, and clear release updates. Keep Product, Sales, and Support in sync with what your software actually does and what changed.
Talk to your coding agents and hear them talk back. SKI runs Claude Code, Codex, Cursor, OpenCode, Antigravity and pi side by side on your Mac, and tells you the moment one needs you.
telemetry.dev shows each run of your AI agent as one trace. Each model call and tool call is a span with its duration, tokens, cost, and error. Prompts and evals use the same traces: change a prompt without a deploy, then run it on a dataset and compare the scores with production. Alerts tell you about errors, cost spikes, and agent loops. Connect with our TypeScript or Python SDK, or with the OpenTelemetry exporter that you already use.
Winneradspy is an ad creative intelligence platform built specifically for mobile app and game marketers. Explore 20M+ ad creatives across 200K+ apps, uncover winning hooks, visuals, messaging and CTAs, and track competitor campaigns with real-time alerts. Unlike generic ad spy tools, it scores creatives as Winner, Loser or Learning, helping UA managers, growth teams and agencies understand what works and build better campaigns. Query ad insights through ChatGPT, Claude or Gemini via MCP.
Backenly is an autonomous backend platform built for coding agents. Your agent builds the backend over MCP, from Postgres to sign-in, storage, functions and realtime. Then it maintains itself: every minute a self-healing loop repairs missing indexes, RLS gaps and dead realtime triggers, verifying each fix live. As your app grows, it restructures its own schema once you approve. Risky changes wait for you, and every change is versioned with rollback.
Make your iPhone Duo screen a creative studio with adjustable screen lighting, a live makeup mirror, color animations, and personal photo displays. LumaFold lets you use two screen areas differently. Light your face while checking your makeup, pair two colors for a creative shot, or combine a favorite photo with a handwritten message. LIGHT FOR YOUR BEAUTY ROUTINE Use the live camera mirror on one side and adjustable light on the other.

Hacker News
Hello HN! Wonderhop is a small browser game with no account needed to play, everyday there are 4 rounds of 7 quesitons like "Name a food that a lot of people hate" The goal depends on the mode: Either gives the answer most people would give, the one no one would give, the oldest answer or the most recent one and there's a leaderboard for the day. The most interesting part of the project was understanding answers that are typed freely and in 10 languages, there was some typos, plurals, nickname,... (124 points, 98 comments).
About 11 months ago i revived the amazing but unfortunately unmaintained spotify-tui. Since then I have been working on it almost non stop, finding a lot of problems on the way. One of the main issues I ran into were the Spotify web API rate limits. Third party clients like spotatui are dependent on a developer app made in the Spotify developer dashboard, which get rate limited a lot and Spotify has slowly been deprecating endpoints from it. The workaround for this used to be using a shared clie... (92 points, 19 comments).
I have been researching what the ultimate diff tool would look like, based on actual diffs in open source repositories. OmniDiff can diff: code (25 languages), config, images, PDFs, archives, cursors, fonts... It's fast. It can diff C++ files of tens of thousands of lines in under 100ms, on a 2023 ThinkPad T14s. It's open source. AGPLv3. It's based on real diffs. I looked at the 7400 repositories that are listed in Gentoo packages, sampled 2000 diffs and solved them manually to get a good unders...

Hi HN, I kept wiring Ben Eater's 8-bit computer wrong, so I built a realistic virtual breadboard editor. Some of the nice features are side-by-side diff, scope, schematics auto-sync, auto-router (BBRouter stands for breadboard router), and my favorites: upload from the real Arduino IDE and connect to your AI with MCP, let Claude & co build it or help you troubleshoot. The link is the SAP-1 running. You can orbit it, probe a hole with the scope, slow the clock down, play with the virtual displays... (46 points, 10 comments).
Hi HN, I'm Ruud, co-founder of Lont. We turn company emails into personalized videos. Video captions cost us manual work twice: fixing misheard words, then fixing layout, like lines ending on “the”. Overtone uses multiple models to listen to the audio: gpt-transcribe, Azure STT, and Elevenlabs Scribe. When they return conflicting results, Overtone sends small clips to the models again, and then lets an LLM decide what was actually said. The LLM is like a human doing a sanity check on the transcr... (45 points, 11 comments).
tl;dr: Agents can play Pictionary. You can connect your own agent, or just watch a game in progress here: https://sketch.wakeshift.ai/games/q5ucru Hi folks! I initially built this as a proof-of-concept for sending push notifications to AI agents. Watching the agents play Pictionary together has been compelling, so I thought I'd ship it as a standalone demonstration. In Sketch Stadium, your agent subscribes to game events. Agents take turns either drawing or guessing. Easy clues are 1 point, medi... (35 points, 11 comments).

Real trained RL policies for the Microduck robot, running fully in the browser: MuJoCo compiled to WebAssembly steps the physics, onnxruntime-web runs the policy network at 50 Hz. No server, no backend. Two locomotion variants of the same robot are included: legs (walking, the default) and rollers (the wheeled skating variant). Press M (or hold D-pad up ~1 s on a gamepad) to switch; the roller model, meshes and policies are lazy-loaded on the first switch. | Mode | Checkpoint | What it does | |--------|-----------|--------------| | Run (legs) | BESTalphawalking.onnx | Velocity-tracking locomotion (arrows / WASD to steer) | | Sit | BESTalphasitstand.onnx | Sits down on its hull, stands back u...

Semantic search for 3D assets: USD + RTX simulation previews SimReady Central USD Search — single-container demo (OpenSearch + Neo4j + Redis + deepsearch-api + asset-graph-service, SigLIP2 embeddings via a local siglip2-triton process — see docker/Dockerfile.hf-space-gpu). Runs on a GPU hardware tier (rtx-pro-6000), unlike the free-tier docker/Dockerfile.hf-space variant, which routes SigLIP2 to NVCF instead. The index itself is pulled from the artifact S3 bucket at container startup, not baked in. Deployed by github.com/NVIDIA-dev/simready-central-indexing-internal's python -m pipeline.run_pipeline deploy-space-gpu. Third-party notices: THIRDPARTYNOTICE.md. SimReady Central is a Hugging Fac...
Video generation with a synchronized soundtrack MiniMax-H3 — unquantized, split across two Spaces Joint video and soundtrack out of a single denoising pass, at bfloat16 with no quantization anywhere. This Space is the denoising half: the 61.73 GiB transformer and the two autoencoders. The 62.14 GiB Qwen3-VL conditioner runs in qwen3vl-conditioner, which this Space calls over the gradio API for every request. The weights are the public MiniMaxAI/MiniMax-H3 diffusers checkpoint. Turbo mode (optional checkbox) applies the larryvrh distillation LoRA at generation time, reducing inference from 25 steps to 7 for ~4× faster generation with minimal quality loss. MiniMax-H3 is 195.9 GiB in bfloat16 a...
