24 alternatives to Handler
Hey HN, I’m Vignesh, solo dev. Handler is a Mac app for Codex and OpenCode that adds a review layer while the agent is generating code. Every edit comes with a short explanation: what changed, why it changed, and what it touches. If one edit needs more context, you can open a side chat on just that change and ask follow-ups without derailing the main agent run. The goal is to build a mental model as the code is generated, instead of waiting until the end and reviewing one giant diff cold. It’s the same idea that makes stacked PRs easier to review: smaller, understandable units. Handler…

We recently shipped the Tiptap AI Toolkit (https://tiptap.dev/docs/content-ai/capabilities/ai-toolkit/o...), which lets developers embed LLM-powered editing into rich text editors. Now we’re exploring the next step: making agents operate on documents without a browser involved. The idea is a server-side system where agents can read, write, and transform documents in real time — essentially treating your document layer as a programmable data store that agents can interact with directly. Internally we’ve been joking about the name “real-time agentic document…

Baton▲106Hi, I built this because running multiple Claude Code agents across multiple IDE and terminal windows was getting messy. Like many, I went from working at one thing at the time, to multiple, and it was all changing quite fast. I needed one place to see all my agents and worktrees, seamlessly switch between them, monitor their status and once their done, review their changes. I also wanted to quickly spin up new agents in isolated worktrees whenever an idea came to mind. I've been building Baton from within Baton for a while now, which has been a pretty fun loop. Would love to hear what you…

Hey HN! We're Charles and Dean. A few weeks ago we posted about Stage, a code review tool that guides you through reading a PR step by step - https://news.ycombinator.com/item?id=47796818. We got a lot of great feedback but also heard from many people that they wanted to have the chapters experience even before opening a PR… so we built the Stage CLI as the local, open-source version that anyone can try. Here’s a quick demo video: https://www.tella.tv/video/stage-cli-demo-f55q It works with any coding agent of your choice. The skill instructs the agent to…

Alchemize▲85Hey HN, we’re Robert and Sam. We’re building Alchemize, a code review platform that simplifies PRs to help you ship faster. Here’s a demo video: https://www.tella.tv/video/simplify-pr-reviews-with-alchemiz... Sample to try: https://app.tryalchemize.com/example Agentic coding has 10x’d code output. Teams are opening larger PRs more frequently, but the current tools don’t support this new coding paradigm. GitHub still presents files without structure. As engineers reviewing these massive diffs more frequently, we spent hours painstakingly reconstructing where…

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…

Hey HN! I'm Hussam, a Senior Algorithm Engineer at CodiumAI. We launched PR Agent a little over a year ago — it’s a free and open-source tool that helps with reviewing pull requests. The response has been great and more than 70 contributors have added to the project. Today, we're launching PR Agent as a browser extension. Key features: - AI Chat in PRs: You can ask questions about specific code changes and the context is passed to the AI model - Automated Code Reviews: The /review command does an automated review, focusing on potential bugs, security issues, and best practice violations…
