TellsU

Feedback form for extensions, plugins and apps

Tells you what users think, and what they’re running.

A feedback form your users open from a small bundled widget or a plain link, with your own questions and branding. Every submission arrives with the version, browser, OS and platform details attached.

Why it matters

Feedback with context

Store reviews and support emails rarely say which version someone is running. Installed software lives in many versions at once, and fixes take time to reach everyone, so each report starts with questions: which version, which browser, which host and runtime?

With TellsU, the answers come with the report.

Getting started

How it works

  1. Add it in two minutes

    Bundle the widget that opens your feedback form in your app, your extension’s popup or your plugin’s admin pages, or link to the form from your help menu, emails and README.

  2. Your users see what’s sent

    They pick a feedback type, say what happened and see the environment details that go with it before sending.

  3. Feedback arrives with context

    Every submission lands in your inbox with its version and environment, and is forwarded to your email. On the paid plan, to Slack, Discord or a webhook too.

Platforms

Works where your software runs

  • Browser extensions

    Chrome, Edge and Firefox, in your popup or options page.

Release tracking

Track sentiment, release by release

Every submission carries its version, so the overview shows how people feel about each release, and each bar opens the feedback behind it. Free on every plan.

  • Happy
  • Okay
  • Unhappy
  • No answer
  • 2.4.140 submissions
  • 2.4.053 submissions
  • 2.3.244 submissions

Sample data: a rough release stands out.

Customization

Make the form your own

On every plan, pick your brand color, choose which feedback types to offer, reword the questions and the thank-you, and add a review link. The paid plan adds your logo, screen headings and questions of your own:

  1. Your logo, in place of the TellsU badge
  2. A heading for each screen of your app
  3. Your brand color, in light and dark (every plan)
  4. Your own questions, answered in text, choices or yes/no

Privacy first

Built to be trusted inside your app

  • Bundled, tiny, never loaded remotely

    Under 3.5 kB with no dependencies, shipped inside your package. No new permissions.

  • Sends nothing until clicked

    No config fetch, no analytics, no pings. It opens the feedback page, and that’s all.

  • Old versions keep working

    Widgets and links you’ve already shipped keep working, so users on old versions can still reach you.

  • Your data stays yours

    Export to CSV or delete it whenever you like. Feedback is deleted after 12 months, or sooner if you choose.

Free, with extras if you want them

The free plan has everything that makes TellsU useful, for as long as you like. No card needed.
