Finic – Open source platform for building browser automations▲143
Last year we launched a project called Psychic that did moderately well on hacker news, but was a commercial failure. We were able to find customers, but none with compelling and overlapping use cases. Everyone who was interested was too early to be a real customer. This was our launch: https://news.ycombinator.com/item?id=36032081 We recently decided to revive and rebrand the project after seeing a sudden spike in interest from people who wanted to connect LLMs to data - but specifically through browsers. It's also a problem we've experienced firsthand, having built scraping…

We built an AI to review your pull requests▲53
Hey HN, We’re two developers (co-founders) with a team of 20 who got tired of spending hours reviewing PRs, so we built Infinitcode.ai, an AI-powered code reviewer that: - *Summarizes PRs in plain English*: No more deciphering 1,000-line diff jungles - *Catches more than bugs*: Security holes, performance pitfalls, code smells, even typos (yes, we’ll flag “vurnerabilities” and vulnerabilities) - *Zero onboarding*: Works instantly—no “let me learn your codebase for weeks” nonsense. Why we’re posting: We’re in alpha and need brutal honesty. Roast our tool, mock our UI, or tell us why AI will…

Control Claude permissions using a cloud-based decision table UI▲14
We’ve been building visual rule engines (clear spreadsheet interfaces -> API endpoints that map incoming data to a large number of potential outcomes), and had the fun idea lately to see what happens when we use our decision table UI with Claude’s PreToolUse hook. The result is a surprisingly useful policy/gating layer– these tables let your team: - Write conditional, exception-friendly policies beyond globs/prefixes (e.g. allow rm -rf only in */node_modules/*, deny / or $HOME, ask if --force or network call; gate kubectl delete / SQL DROP with a clear reason) -…

CyScout – Solidity Vulnerability Detection Powered by GitHub CodeQL▲13
Hi everyone, GitHub's CodeQL is a powerful semantic code analysis engine for identifying vulnerabilities across codebases. We've extended CodeQL to support Solidity, the most popular programming language for smart contracts. CodeQL enables you to query code as though it were data, and it's open-source (OSS). You can check it out here: . The product page is available at . CodeQL has its own licensing model, which you can find at https://codeql.github.com/. TL;DR: CodeQL is free for research and open-source projects.
