They serve completely different needs—Cognition replaces a junior engineer, Puck replaces a CMS editor.
Can Cognition AI replace a human developer completely?
No. Devin is designed to automate engineering tasks but requires human oversight. It handles multi-step tasks and triage but is not a replacement for high-level design and decision-making.
Is Puck only for React projects?
Yes, Puck is built specifically for React.js and requires a React environment to render components. It works with Next.js and other React frameworks.
Does Devin work with frontend code only?
No. Devin is a general-purpose autonomous engineer that can write backend, infrastructure, and frontend code. It supports Windows VM and Android emulator for full-stack builds.
Can I host Puck myself for free?
Yes, Puck is MIT licensed and can be self-hosted entirely for free. You only need to pay if you use Puck Cloud features like AI, versioned storage, or collaboration.
What is the FrontierCode evaluation in Devin?
FrontierCode is a new evaluation that measures whether code is merge-worthy (production-ready) rather than just syntactically correct, raising the bar for autonomous code quality.
What are the new file attachments in Puck AI?
Puck AI 0.7 added the ability to attach images, PDFs, and text files to chat prompts, allowing the AI to generate pages informed by uploaded content.
Does Cognition AI offer a free tier?
Cognition AI is freemium, but the free tier details are not publicly specified. Enterprise plans are likely tailored and backed by the productivity guarantee.
Which tool is better for a non-developer content editor?
Puck is designed for content editors with a drag-and-drop interface constrained to developer-ready components. Cognition AI is intended for engineering teams writing code.
