Show HN: SpecterQA – AI personas test your web app, no scripts needed

Hacker News - Mon, 02/23/2026 - 10:53am

SpecterQA is an open-source CLI for behavioral testing. Instead of writing test scripts with selectors, you define personas (YAML) and journeys (goals). The engine launches a real browser via Playwright, screenshots the page, sends it to Claude's vision model, and the AI decides what to click/type/scroll. Loop until done or stuck.

The idea: test scripts break when markup changes. Vision-based tests break when the UX actually breaks.

Personas have attributes like technical comfort, patience, and role that shape navigation behavior. A "frustrated non-technical admin" navigates differently than a "power user developer."

pip install specterqa specterqa init specterqa run -p demo Cost: ~$0.30-$3.00/run depending on journey length. Built-in budget caps. Requires Anthropic API key.

Previously called GhostQA — we rebranded after discovering ghostqa.com exists as an AI testing company. Clean break, no confusion.

Show HN: TTSLab – A voice AI agent and TTS lab running in the browser via WebGPU

Hacker News - Mon, 02/23/2026 - 10:52am

I built TTSLab — a free, open-source tool for running text-to-speech and speech-to-text models directly in the browser using WebGPU and WASM.

No API keys, no backend, no data leaves your machine.

When you open the site, you'll hear it immediately — the landing page auto-generates speech from three different sentences right in your browser, no setup required.

You can then try any model yourself: type text, hit generate, hear it instantly. Models download once and get cached locally.

The most experimental feature: a fully in-browser Voice Agent. It chains speech-to-text → LLM → text-to-speech, all running locally on your GPU via WebGPU. You can have a spoken conversation with an AI without a single network request.

Currently supported models: - TTS: Kokoro 82M, SpeechT5, Piper (VITS) - STT: Whisper Tiny, Whisper Base

Other features: - Side-by-side model comparison - Speed benchmarking on your hardware - Streaming generation for supported models

Source: https://github.com/MbBrainz/ttslab (MIT)

Feedback I'd especially like: 1. How does performance feel on your hardware? 2. What models should I add next? 3. Did the Voice Agent work for you? That's the most experimental part.

Built on top of ONNX Runtime Web (https://onnxruntime.ai) and Transformers.js — huge thanks to those communities for making in-browser ML inference possible.

Show HN: Restrict Kiro CLI access to your sensitive files

Hacker News - Mon, 02/23/2026 - 10:01am

Hi HN, I published a small open-source wrapper for Kiro CLI that prevents it from accessing your project's sensitive files (secrets, credentials, properties) at the OS level. Feel free to test it, share feedback, or contribute!

Pay attention to the snow on your roof. If you don't clear it off in a timely manner, you're asking for trouble.
