Pros & Cons
Pencil Project
Pros
Completely free with no subscription or account required
Works fully offline as a native desktop application
Simple, low-fidelity sketch style is fast for early-stage wireframing
Open source under GPL, so the code can be inspected or modified
Lightweight compared to full cloud design suites
Cons
No real-time multiplayer collaboration found in modern tools like Figma or Penpot
Development pace has historically been slow, with long gaps between releases
Lacks design tokens, component variants and advanced prototyping interactions
Interface and stencil library feel dated compared with current design tools
No official cloud sync, version history or team management features
reviewstudio
Pros
Supports proofing and markup across a wide range of file types, including images, video, audio, PDF, documents, HTML, and 3D
Free Starter plan plus a 30-day full-featured trial with no credit card required
Built-in workflow automation and approval tracking to speed up sign-off cycles
Native integrations with common project-management and file-storage tools (Asana, Monday, Wrike, Dropbox, Kantata)
Enterprise tier offers SSO, a custom domain, and dedicated support for larger organizations
Cons
The Advanced plan requires a minimum of 5 users, which may be costly for very small teams
Workflow automation and API access are gated behind the higher-priced Advanced/Enterprise tiers
Enterprise pricing isn't published and requires contacting sales
Storage and active-review limits on entry-level plans may require an upgrade for high-volume creative teams
