Craft Agents OSS is a free, Apache-licensed desktop app and CLI framework for building and running AI agents against real-world workflows. Built by the team behind the Craft.do document editor, it connects to 32+ integrations out of the box — MCP servers, REST APIs, Google Workspace, Slack, GitHub, and local filesystems — with no manual configuration required. It supports Anthropic, OpenAI, Google AI, and any OpenAI-compatible backend in a single unified UI. The core idea is an "agent canvas" where users drag tools onto a timeline, set up triggers, and watch agents execute multi-step workflows in real time. It also ships a headless server mode, making it usable as a remote agent runner in CI/CD pipelines or staging environments. The project hit 4,200+ stars on GitHub within 24 hours of launch. What distinguishes Craft Agents from similar tools like Dify or n8n is its desktop-first UX and tight integration with Claude's computer-use and agent loop capabilities. The Craft team has deep product experience — this isn't a weekend hack but a polished tool with well-documented agent primitives, error handling, and rate limiting built in from day one.

AI browser automation that doesn't break every other deploy

Libretto is an open-source TypeScript toolkit for building and maintaining browser automations that are actually reliable. Unlike most AI-driven browser tools that use probabilistic reasoning to select elements at runtime, Libretto works by having the AI generate deterministic selectors and action sequences upfront — then executing them with zero LLM involvement at runtime. The AI is your authoring tool, not your runtime dependency. The core insight: most AI browser automations fail in production because they call an LLM on every page interaction. Libretto flips this by using AI to write and update the automation scripts, but running them as ordinary code. When a site changes and your automation breaks, Libretto detects the failure and prompts you to let AI update the selector — then it's deterministic again. Built by the team at Saffron Health, the library hit HN's front page today and is generating discussion as a more pragmatic alternative to fully autonomous browser agents. For anyone who's tried Playwright with AI wrappers and found them unreliable in CI/CD, this is the architecture that's been missing.
Reviewer scorecard
“This is the missing middle layer between raw SDK calls and fully managed platforms. 32 integrations with zero config and a headless mode means you can drop it into an existing workflow in under an hour. Apache 2.0 license is the cherry on top.”
“This is the right mental model for production browser automation. Using AI for authoring but not runtime means you get consistency in CI without random failures at 2am. I've been waiting for someone to build this properly.”
“The 4k stars in 24 hours is impressive but hype-fueled. We've seen a dozen 'universal agent frameworks' launch in the last year — most get abandoned once the novelty wears off. Wait to see if the integration library is actively maintained before betting your workflows on it.”
“The 'AI updates your selectors' workflow sounds great until you're reviewing 50 AI-generated selector changes after a site redesign. You've just moved the flakiness from runtime to the maintenance loop. Also, 37 stars is very early — I'd wait for production case studies.”
“Desktop-native agent runners are the 2026 equivalent of the browser as the universal platform. The Craft team's product pedigree and the open-source architecture mean this could become the go-to scaffolding for agent apps the way Electron became the default for desktop apps.”
“The deterministic-at-runtime pattern will become the standard architecture for AI-assisted automation. Libretto is arriving exactly as enterprises start demanding reliability SLAs from their AI tooling. Early movers will have a significant advantage.”
“Finally, an agent tool designed by people who actually care about UX. The drag-and-drop canvas is the first agent builder I've used that didn't feel like configuring XML. Non-engineers on my team were running their own agents in about 20 minutes.”
“As someone who automates repetitive web tasks constantly, this solves my biggest frustration — AI-written automations that fall apart the moment a site updates their CSS. The auto-repair loop is exactly what I need for long-running workflows.”
