We just open sourced GAE/Bingo, a re-imagining of patio11's A/Bingo for use in App Engine (w/ his approval).

It should get anyone on App Engine (python) up and running and A/B testing in minutes -- if you have trouble please let me know. Does its best to maintain identities as users transition from anonymous to logged-in, persists experiment results to the datastore in the background, etc.…

QualGent▲296I built an AI agent that can do mobile app QA after working at Google for years and waiting weeks for QA results. It runs on real devices and uses an ensemble of agents (including computer use) to test like a human. Happy to answer questions and hope it helps app devs ship faster without bugs!

Hey, Jared Palmer (creator of this playground) here. Really excited to ship this. I’ve been building this over the past few weeks to compare LLMs from different providers like OpenAI, Anthropic, Cohere, etc. At Vercel, I manage our Frameworks division (including Next.js, Svelte, and Turbo) and wanted to also dogfood some of the latest features in a slightly larger application. This playground takes a lot of inspiration from https://nat.dev and is built on Tailwind, ui.shadcn.com, and some upcoming Vercel products we’re announcing soon. We’re going to continue adding models to…

Quash▲151Hey HN, I’ve been working on Quash, a mobile-first QA tool where you can write test flows in plain English and have an agent execute them on real Android devices. We’ve finally shipped a downloadable desktop app (macOS, Intel + Apple Silicon), and you can try it now. No managed “demo” environment – it runs tests against your own apps and devices. (Can connect any device locally as well)

I built this out of frustration as I lead the development of AI features at Yola.com. Prompt testing should be simple and straightforward. All I wanted was a simple way to test prompts with variables and jinja2 templates across different models, ideally somthing I could open during a call, run few tests, and share results with my team. But every tool I tried hit me with a clunky UI, required login and API keys, or forced a lengthy setup process. And that's not all. Then came the pricing. The last quote I got for one of the tools on the market was $6,000/year for a team of 16 people in a…

Introducing gamium, a game test automation SDK for game developers and qa engineers. There are tools such as Selenium and Appium for web and mobile, and they are used universally, but in games, there are many areas where tests are not automated, so it was developed to solve this problem. gamium currently supports unity engine, and supports python and typescript as client languages. We plan to support various engines such as unreal and godot in the future. We look forward to your interest and comments. Thank you.
