For Developers
Save docs before they go stale.
The internet forgets. You shouldn't have to.
API docs get deprecated without notice. Stack Overflow answers get deleted. Library READMEs change and break your mental model. Backdrop gives you a permanent personal archive of the technical knowledge you rely on, searchable when you need it most.
Full HTML capture
Archive documentation pages with full fidelity HTML — code blocks, formatting, and all — not just plain text.
Readable text extraction
Strip nav and sidebars for a clean, focused view of just the technical content you care about.
Full-text search
Search across every word of every archived page. Find that error message solution you saved six months ago.
Version-aware archiving
Archive docs at specific versions. Never lose track of what a library's API looked like when your code was written.
Browser extension
Archive any page instantly from Chrome or Firefox without breaking your dev workflow.
Collections for projects
Group archives by project, tech stack, or team. Share collections as onboarding resources.
