Is Tweak a free Ruttl alternative?

For the core visual-feedback workflow on live web pages, yes. For Ruttl's project workspaces, version history, and live edit mode, no. Those are paid-tier features Tweak intentionally doesn't replicate.

Does Tweak support PDFs or static images?

No. Tweak is for live web pages. Ruttl supports PDFs and image files alongside web annotations. If you need that mix, Ruttl is the better fit.

Can Tweak compare two versions of a page?

Not natively. Ruttl has built-in version comparison; Tweak is a single-state tool. You'd handle versioning by sharing two separate annotation links, one per version.

Is Tweak open source like Ruttl?

Tweak is open source on GitHub and self-hostable on Cloudflare Workers. Ruttl is closed-source SaaS.

Tweak vs Ruttl

Bottom line: Choose Tweak for free, instant visual feedback with no project setup and no paid tier. Choose Ruttl if you run an agency that needs project workspaces, version comparison, live CSS edit mode, and PDF/static-image annotation alongside web pages.

Tweak and Ruttl both annotate live websites with comments and drawings. Ruttl adds a project-workspace layer with version history, side-by-side comparison, and a "live edit" mode where reviewers can suggest CSS/text changes inline. Tweak is the simpler, free, open-source alternative. Link-based sharing, real-time cursors, no project hierarchy.
