Assignment Tracker for Canvas

A free, open-source browser extension for students who use Canvas LMS. On a course's Assignments page it shows, at a glance:

• Which assignments are not at full points yet: "85/100 · 15 pts left"
• Availability: Open, Closed, Not yet available (by date or by module), Overdue
• Other states: Missing, Late (with deducted points), Submitted · awaiting grade, Grade not posted, Excused, Retry available, and ungraded / 0-point assignments (never flagged as missing points)

It adds a small badge to each assignment row and a collapsible summary panel with filters: Not at 100%, Open, Overdue, Closed, Pending grading, All.

Privacy in one paragraph

The extension reads your assignments from the Canvas site you are already logged in to, using that site's own API with your existing session. It never asks for a password or API token, never contacts any other server, has no analytics or telemetry, and loads no remote code. It only sends GET (read) requests: it cannot submit, edit, or delete anything. See PRIVACY.md.

Install

From a release (recommended, nothing else to install):

1. Go to the latest release and download assignment-tracker-chrome-<version>.zip (or the Firefox zip).
2. Unzip it and keep the folder somewhere permanent; the browser loads the extension from it.
3. Chrome / Edge / Brave: open chrome://extensions, turn on Developer mode, click Load unpacked, and select the unzipped folder (the one containing manifest.json).
4. Firefox 140+: open about:debugging#/runtime/this-firefox, click Load Temporary Add-on…, and pick the zip. Temporary add-ons are removed when Firefox restarts.

To update, replace the folder's contents with the new release and click ↻ on the extension.

Install from source

Requirements: Node.js 22.12 or newer.

git clone https://github.com/davidmenendez9901/assignment-tracker-for-canvas.git
cd assignment-tracker-for-canvas
npm install
npm run build

This produces dist/chrome and dist/firefox.

Chrome / Edge / Brave

1. Open chrome://extensions and turn on Developer mode.
2. Click Load unpacked and choose dist/chrome.

Firefox (140 or newer)

1. Open about:debugging#/runtime/this-firefox.
2. Click Load Temporary Add-on… and choose dist/firefox/manifest.json.
3. If Firefox shows the extension needs permission for instructure.com, allow it from the extensions menu.

Then open any course's Assignments page in Canvas.

Using it with a custom Canvas address

Works automatically on *.instructure.com. If your school uses its own address (for example canvas.myuniversity.edu):

1. Open that Canvas site and click the extension's toolbar icon.
2. Click Enable on this site. A settings tab opens with the address filled in.
3. Click Allow and accept your browser's prompt.
4. Reload the Canvas tab.

You can also add or remove addresses any time from the extension's Options page. Access is granted per site, and only the site's /courses/… pages are used.

What the statuses mean

Badge	Meaning
85/100 · 15 pts left	Graded below full points. Late penalties are already included in the score.
100/100 (subtle)	Full points (or +X extra for extra credit).
Due in 3 days / Due in 5 hours	Open and not submitted yet. Highlighted when due within 48 hours.
Overdue	Past the due date, still open, nothing submitted. Only for online submissions.
Missing	Canvas (or your teacher) marked it missing.
Late (−5)	Submitted late; points deducted by the late policy.
Closed / Closed · not submitted	Past the "available until" date, or locked.
Opens Mar 20 / Locked (module)	Not available yet: by date, or until you complete a module's requirements.
Submitted · awaiting grade / Awaiting regrade	Submitted and not graded yet, or resubmitted after grading.
Grade not posted	Graded, but your teacher hasn't released the grade yet.
Excused / No points	Doesn't count; never shown as missing points.
Retry available (1/3 used)	Limited attempts remain and it's still open.

"Not at 100%" includes graded-below-full, incomplete, missing, overdue, and closed-without-submission assignments. Work that isn't due yet is not counted (it's under Open).

npm test           # unit + DOM tests (Vitest)
npm run check      # typecheck, lint, test, build
npm run zip        # package release/ zips (after build)

Layout:

src/core      pure classification/formatting logic (no DOM, fully tested)
src/api       read-only, same-origin Canvas API client
src/content   content script: panel, badges, row matching, theming
src/shared    custom-domain permission + script registration
src/background, src/popup, src/options
manifests/    base.json + chrome.json / firefox.json overrides

See CONTRIBUTING.md.

Known limitations

• Canvas changes its page markup from time to time. If badges stop appearing, the summary panel still works; please open a "Canvas compatibility" issue.
• Dates are compared in absolute time and shown in your browser's time zone, which may differ from your Canvas profile time zone.
• The panel lists all assignments in the course (including other grading periods); a checkbox lets you hide ones not listed on the current page.
