Open source alternatives to Arc

2 projects on starwire do the same job. Ranked by how much of what Arc does each one covers, read from its README and website. Ties go to the most active.

What Arc does

  2. Sidebar tabs and spacescore
  3. Pinned tabs and folders
  4. Split view
  5. Command bar
  6. Profiles
  7. Ad and tracker blocking

Each dot in the table is one job, in this order. Square dots are core jobs and count double. Full means yes, half means partly. "See the evidence" under a project shows the line behind each one. Coverage is what a project documents, not how well it works or how hard it is to move to. How we score this
