Frequently Asked Questions
Open Design vs Cognition AI: which should you choose?
Choose Cognition AI if you lead an enterprise engineering team that needs autonomous bug triage, legacy modernization, and guaranteed productivity gains backed by a $10M guarantee. Choose Open Design if you are a solo builder or designer who wants to rapidly generate production-ready designs and prototypes locally, with full control and no vendor lock-in. They serve different roles: Devin is a full-time autonomous engineer; Open Design is an open-source design engine.
Which tool produces higher-quality code?
Cognition AI's Devin is built for enterprise production code with FrontierCode evaluation measuring merge-worthiness. Open Design focuses on design artifacts (HTML, PDF, etc.) rather than backend code quality.
Can I run these tools locally?
Open Design is local-first and runs entirely on your machine. Cognition AI's Devin is cloud-based, though Devin Desktop provides a local IDE.
Do I need API keys for Open Design?
Yes, you bring your own API keys (BYOK) for the 21+ supported agents. The free tier requires you to have your own keys.
Which tool is better for solo developers?
Open Design is more accessible for solo developers given its free BYOK model and focus on design generation. Devin is enterprise-oriented and likely overkill for personal projects.
Does Cognition AI have a productivity guarantee?
Yes, Cognition AI recently announced a $10M AI Productivity Guarantee for enterprise customers, ensuring measurable productivity gains.
Can Open Design generate video?
Yes, Open Design can generate HTML video (MP4) from prompts, as part of its design artifact output.
Which tool integrates with Slack and Jira?
Cognition AI's Devin integrates directly with Slack, Jira, Linear, and Datadog for automated bug triage and task management. Open Design does not offer these integrations.
Is Open Design truly open source?
Yes, Open Design is licensed under Apache-2.0, meaning you can modify and distribute it freely.
