Best alternatives to Vecti in 2026

Designing a website or app usually means several people — a designer, a product manager, maybe a developer — need to look at the same screen mockups and leave comments or make tweaks without stepping on each other's work. Vecti is a tool that runs entirely in your browser and lets a small team do exactly that: draw interface screens, snap elements to a precise grid, and see each other's cursors move live, the same way Google Docs lets people co-write a document. Vecti is built by a solo developer with close to two decades of UI/design experience, and it positions itself as a performance-focused alternative to Figma and Sketch. Under the hood it emphasizes a high-performance rendering engine so large files stay responsive, pixel-perfect grid snapping for precision layout work, a shared asset library, and permission-based sharing that separates editors (who pay) from viewers (who are unlimited and free). It also includes a presentation mode for full-screen client reviews. Reusable components — the building block most design systems rely on — are listed as "coming soon" rather than shipped, which is a meaningful gap versus Figma today.
