24 alternatives to JACoB – Open-Source AI Coding Agent for Real-World Productivity
Hi, we're Kevin, Chris, and Brian, the creators of JACoB (Just Another Coding Bot), an open-source AI coding agent designed to streamline the development process. As veteran developers, we know that while AI isn't perfect, it can be a valuable tool for tasks like code reviews, converting designs to React components, and writing high-quality GitHub issues. We’ve been building JACoB over the past year to assist with our real work, and today we’re open sourcing it under an Apache 2.0 license. Our goal is to create the first fully open-source tool that matches the quality and polish of many…

Zencoder ▲766Hi HN, I’m Andrew, Founder of Zencoder. While building our IDE extensions and cloud agents, we ran into the same issue many of you likely face when using coding agents in complex repos: agents getting stuck in loops, apologizing, and wasting time. We tried to manage this with scripts, but juggling terminal windows and copy-paste prompting was painful. So we built Zenflow, a free desktop tool to orchestrate AI coding workflows. It handles the things we were missing in standard chat interfaces: Cross-Model Verification: You can have Codex review Claude’s code, or run them in parallel to see…

CodeWords▲385Hey HN, Aymeric here, co-founder of Agemo and maker of CodeWords. Generating nice-looking UIs with AI has been democratized now thanks to tools like Lovable, v0 and bolt. Going from natural language to a complex back-end workflow is still an unsolved problem. We started our journey by researching neurosymbolic methods applied to software/code generation problems and it landed us a feature in the ARC-AGI report last year (https://arxiv.org/abs/2412.04604). We've now applied this research to build an AI-native workflow automation platform to enable builders of any…

Hey HN! I’m Dane, the creator of Plandex (https://github.com/plandex-ai/plandex), an open source AI coding agent focused especially on tackling large tasks in real world software projects. You can watch a 2 minute demo of Plandex in action here: https://www.youtube.com/watch?v=SFSu2vNmlLk And here’s more of a tutorial style demo showing how Plandex can automatically debug a browser application: https://www.youtube.com/watch?v=g-_76U_nK0Y. I launched Plandex v1 here on HN a little less than a year ago…

WOZCODE▲194For the last year we've been building an AI mobile app builder. Last week we decided to generalize our agent harness and benchmark it against vanilla Claude Code. Turns out the tools we built for app building were significantly more efficient than the native Claude Code tools. When we ran benchmarks we beat Claude code on speed (~40% faster) , cost (25-55% cheaper) and performance (+17% on Terminal Bench 2.0). Today we're making our agent harness publicly available as a Claude Code plugin. Use code WOZCODE1 to try it for $1 at wozcode.com

display.dev▲183Last week's post from Thariq "The Unreasonable Effectiveness of HTML" went viral in X. He made a good point about HTML being the more expressive and human friendly alternative to markdown files. I completely buy in where he's coming from, I've been asking Claude Code to create me HTML files to better understand what we're planning and building together. What Thariq didn't address was the part of sharing and collaborating on these HTML artifacts (he proposed uploading to S3). While I've been heavy user of HTML artifacts to share quarterly plans, implementation specs, technical guides and…

Boxes.devfree tier, from $19/mo▲112Hi HN, we’re Nick and Drew, and we’re building boxes.dev – the first cloud-only agentic dev environment (ADE) that gives every Codex and Claude Code agent its own cloud computer. We’re two engineers who previously built Gem (co-founder/CTO and first hire), and we spent the last year coding almost exclusively using Codex and Claude Code. It’s been a huge change to how we code, and it’s been exhilarating seeing the models keep getting better – but we eventually realized that developing on localhost was holding us back: - Git worktrees are clunky to set up and use for parallelizing work -…

We just launched Gabriel Operator — a browser-based platform that transforms your screen activity into fully executable AI agents. You simply record what you do in the browser, and we turn it into a repeatable agent that runs like a workflow—no APIs, no code. What makes it different? • Works entirely off your screen (great for websites without APIs) • Agents can loop, branch, and request input • You can publish & monetize your automations • Fully web-based, no installation needed Next week, we’re rolling out Creator Mode — allowing anyone to publish, share, and sell their own “Digital…

OpenMolt▲132Hi HN! I built OpenMolt, an open-source framework for creating programmatic AI agents in Node.js. Instead of wiring complex workflows (that can break), you define agents in code with instructions, tools, integrations, and memory. The agent then plans steps and executes actions like calling APIs, updating data, or interacting with services. When things break or change, the agent can adapt instead of failing like static workflows. The goal is to make agents behave more like real software systems than prompt scripts. It includes: - a planning/execution loop - tool and API integrations -…

I created vibescaffold.dev. It is a wizard-style AI tool that will guide you from idea → vision → tech spec → implementation plan. It will generate all the documents necessary for AI coding agents to understand & iteratively execute on your vision. How it works: - Step 1: Define your product vision and MVP - Step 2: AI helps create technical architecture and data models - Step 3: Generate a staged development plan - Step 4: Create an AGENTS.md for automated workflows I've used AI coding tools for awhile. Before this workflow (and now, this tool), I kept getting "close but not quite" results…
