Why Is Tana So Slow to Load?

Ongoing Web, Mac, Windows, Linux Updated October 21, 2026

Quick answer

Tana loads your whole workspace into memory, and the browser version reloads all data every time you open a tab. Switching to the desktop app and avoiding many open browser tabs is the fix that helps most.

Most likely fix: Use the desktop app.

Symptoms

Long startup spinner, slow first search, laggy navigation in big workspaces, or each new browser tab taking a long time to become usable.

Why it happens

  • Whole workspace loaded into memory at startup
  • Browser version reloading all data per tab
  • Very large imported graphs in one workspace
  • Local search index being built after entering offline mode

How to fix it

Try these in order — the most common fix is first.

  1. 1. Use the desktop app

    1. Install Tana Outliner Desktop from outliner.tana.inc
    2. Use it instead of browser tabs; Tana's docs say it loads faster
    3. Use its native tabs and split panels rather than extra browser tabs

  2. 2. Keep one Tana tab open in the browser

    1. Close duplicate Tana tabs
    2. Navigate inside the app instead of opening links in new tabs
    3. Run 'Reset "Always open in..." preference' if links keep opening in the browser

  3. 3. Split huge imports into separate workspaces

    1. Keep archives from Roam, Notion or Logseq in their own workspace
    2. Only open the workspaces you use daily

  4. 4. Wait for the offline index to finish

    1. After choosing 'Work offline', allow a few minutes for the local search index to build in large workspaces
    2. Search will be fast once it completes
