Stably
Stably
Stably is an AI-assisted browser and end-to-end testing platform for software teams. Users describe customer workflows in plain language or record them, then create reviewable Playwright tests and run them in Stably Cloud or their existing CI pipeline.

It can identify test drift and propose repairs as web interfaces change, with updates reviewed through Git pull requests rather than applied silently. Stably supports QA professionals, product managers, and engineers who need to create, execute, and maintain browser-based checks for web applications, including release regression, checkout, authentication, forms, and other multi-step user journeys. Teams can connect test coverage to repositories, Jira tickets, and product documentation, and use Playwright code within familiar development workflows.Starting Price: $0/month -

SymbolHound
SymbolHound
SymbolHound is a search engine that doesn't ignore special characters. This means you can easily search for symbols like &, %, and π. We hope SymbolHound will help programmers find information about their chosen languages and frameworks more easily. SymbolHound is primarily a programming search engine. Searching for symbols is just not that useful for the average Internet user. Google could probably very easily do this, but it wouldn't make their search engine any better for the vast majority of their user base; in fact, it might make it worse. But for the small percentage of people who find themselves needing to search for special characters, Google is not useful. However, SymbolHound is a symbol search engine and is perfect for that query. -
