EVONX vs FlowSnap

EVONX is a web-based multi-agent AI platform for changing existing software or starting an application from a plain-language request. It examines code and dependencies across frontend, backend, infrastructure, and data layers, then turns a feature, change, or fix into a technical plan. It applies the proposed code changes, tests them, and presents a running preview. Work takes place in isolated previews; changes become pull requests only after approval, and EVONX says it does not write directly to the main branch. It can coordinate work across multiple repositories while maintaining their contracts, and its documentation describes generating a working web app and API from a description. The integrations hub provides build-with guides for services including GitHub, PostgreSQL, Stripe, and OpenAI; these are not official partnerships. Customers supply credentials and keep operational ownership of external services. The free Starter plan includes 500 credits per month. Plus costs $20 a month, Pro costs $99 a month, and Enterprise has custom pricing. Heavier models and longer tasks use more credits.

FlowSnap turns app screenshots into sitemaps and user-flow diagrams for product managers, UX designers, and indie developers. Its infinite canvas supports panning, pinch zoom from 10% to 200%, color-tagged cards, and text annotations. A project can import up to 50 screenshots from a photo library or Google Drive. Users can connect cards with solid or dashed lines, customize connection colors, and label transitions. Optional AI tools analyze screenshots, suggest connections, and generate a Markdown sitemap summary; they require the user's Claude API key and send screenshots to Anthropic's Claude API. Projects are stored locally and can optionally sync to a FlowSnap folder in Google Drive, while the listing says FlowSnap does not store project data. Exports include PNG, PDF, SVG, JSON, and Markdown. The free plan allows three projects and adds a watermark to PNG exports. FlowSnap Pro costs $2.99 a month or $19.99, paid once, with unlimited projects, PDF export, watermark-free PNG, SVG, and priority AI features. Supported platforms are Android, iOS, and macOS.
