Pinned to the element, not just the page
Reports remember the exact element and page. Open the site again and the pins are right where the problem is, for everyone on the project.
New Works with Claude Code & Codex
Website feedback your developers can actually fix.
Clients click on the problem. mumus captures the screenshot, the exact element, the browser and the console errors, and puts a clean task on your board. No more “it's broken” e-mails.

How it works
From “something looks off” to a fixable task in three steps.
-
Install the extension
Add mumus to Chrome, Edge or Brave and log in once. It only gets access to the websites of your projects.
-
Click what's wrong
Pin any element on the live page or record your screen. The screenshot and technical details are attached automatically.
-
Fix it on the board
The report lands on your Kanban board with everything a developer needs. Status changes notify the reporter.
Features
Everything between the bug and the fix.
Screenshots & screen recordings
Full screenshots or a short video of the tab, uploaded with the report. Files are private to the project.
Technical context, automatically
Browser, viewport, console errors and failed network requests. Tokens and passwords are redacted before upload.
A board that fits your process
Custom columns, epics with due dates and budgets, tags, estimates, multiple assignees and an archive.
Clients welcome
Invite clients as reporters. They can report and comment, and optionally see only their own tickets.
Notifications that matter
In-app and e-mail per event, mute per project, and an SMS when something becomes critical.
Find anything
Full-text search across titles, descriptions and comments, with filters for epics, tags and due dates.
AI assistants
Your bug reports, inside Claude Code and Codex.
mumus includes an MCP server. Your coding assistant can read a report, look at the screenshot, fix the code and move the card to review, with the permissions you choose.
- Read-only by default. Commenting and editing are separate permissions.
- Limit a token to selected projects. Your role still applies.
- Every change is labelled “via AI assistant” in the history.

Agencies
One organization per client or one for all: projects, roles and client access are separate. Clients report without learning a new tool.

QA and stakeholders report straight from staging. Developers get reproducible tasks with console logs instead of meetings.
Freelancers
Collect your client's feedback during acceptance testing, prioritise it and show progress on a shared board.
Security & privacy
Built for client work, so built to be careful.
Two-factor login
TOTP and backup codes, and organizations can make 2FA mandatory.
Least-privilege extension
It only reaches the websites you add to a project, and asks before each one.
Private files
Screenshots and videos open only after login and with access to that project.
EU hosting
Data stays in German data centres. A data processing agreement is available.
FAQ
Questions, answered.
Does it work on any website?
Yes, on any site you add to a project, including staging and local development servers. The extension asks for permission per website.
Do my clients need an account?

Which browsers are supported?
Chrome, Edge, Brave and other Chromium browsers. The web app works in every modern browser.
What does the extension collect?
Only when you send a report: the screenshot or recording, the page address, the pinned element, browser details and recent console and network errors. Secrets are redacted. See the privacy policy.
What does it cost?
One plan with every feature and unlimited users: €49 per month billed annually, or €69 monthly (excl. VAT), after a 14-day free trial. See pricing. Dedicated instances are available on request.
