Compared honestly · updated 2026-09-26
Nimbus Screenshot is now FuseBase. If you came here looking for the old tool, this is the way out.
Nimbus Screenshot was a million-user capture extension. Its original listing has been renamed and delisted, and the current product, FuseBase Capture, sits behind a sign-in and a workspace subscription that starts at $32 a month, with reviews describing features that used to be free now locked and no self-service way to cancel. Darkroom does the capture-and-annotate part locally, with no account, for free.
- Nimbus Screenshot's original Chrome listing (1,000,000 users) was renamed and is no longer available; the successor has 10,000 users and a 3.6 rating.
- FuseBase Capture routes you to sign in; plans start at $32/month; reviews describe full-page capture moved behind the paywall and no way to cancel auto-renewal.
- Darkroom: no account, no server, capture and annotate free, Pro $12 once. Manifest requests four permissions and no host access.

Where Nimbus Screenshot users get hurt
The listing you installed is gone
The original Nimbus Screenshot extension ID, with a million users and 17,000 ratings, was renamed "Nimble Capture" and last updated in September 2024; the Chrome Web Store now returns nothing for it. The current capture product is "FuseBase Pro - Capture screenshots and Video record" with 10,000 users and a 3.6 rating.

What Darkroom does instead
Darkroom captures a region, the visible page, or the full page, and opens a local editor: arrow, box, ellipse, text, highlight, crop. Copy or save as PNG. Everything lands in a local library in your browser's own storage. There is no sign-in because there is no server. The free library keeps 50 captures; Pro keeps 5,000 and adds blur/redact, numbered callouts, PDF export and search for $12, once.
The manifest requests activeTab, scripting, storage and unlimitedStorage, with no host permissions. Nothing is uploaded, and export of your own screenshots is free forever.

To be fair to Nimbus Screenshot
FuseBase is a team knowledge platform, and screen capture is one piece of it: video recording, cloud editing, sharing and collaboration are things Darkroom does not do. If you need screen recording or a shared workspace and you are willing to run a subscription, FuseBase is a different category of product. Darkroom replaces the old Nimbus Screenshot, not FuseBase.
Try Darkroom
Free on the store. No account, no server, nothing uploaded. Pro is a $12 one-time purchase, sold through Paddle, and plain export of your own data is never paywalled.

- No. Pro is a one-time $12 purchase through Paddle. There is no renewal.
- Does Darkroom need an account?
- No. There is no account, no server and no sign-in. A Pro licence is a key you paste in, verified offline.
