Two Free Extensions for the Community

[Khurram_Shahzad]

Hi everyone,

I have been working on two free, open-source extensions for Manager.io and would love the community to test them and share honest feedback.

────────────────────────────────────────

① Manager.io Developer Toolkit

Try it: https://ksl1816.github.io/manager-developer-toolkit-extenstion/
Code: https://github.com/ksl1816/manager-developer-toolkit-extenstion

This tool is for anyone who wants to build their own Manager.io extension but does not know where to start with the API or coding.

How it works:

-> Load any Manager.io endpoint (customers, invoices, inventory, reports…)
→ The toolkit inspects the live data and shows you every available field
→ Select the fields you want, describe what you want to build
→ Click Generate — it produces a complete, ready-to-paste AI prompt
→ Paste into Anthropic Claude, OpenAI ChatGPT, or Google Gemini
→ Get back a fully working extension HTML file
→ Install it in Manager.io or host it free on GitHub Pages in minutes

No coding knowledge required for basic use. Developers will get even more out of it.

② Sales Analytics Dashboard

Try it: https://ksl1816.github.io/manager-io-sales-analytics-dashboard/
Code: https://github.com/ksl1816/manager-io-sales-analytics-dashboard

This extension was built entirely using the Developer Toolkit above — I loaded the sales invoice endpoint, selected the fields, generated the prompt, pasted it into an AI, and deployed the result.

It is a real example of what the toolkit produces.

What you get:

-> Day-by-day sales breakdown for any month
→ Best and worst day highlighted automatically
→ Month-to-month comparison with charts and difference table
→ KPI cards — grand total, averages, best month, active days
→ Automatic trend insights — upward, declining, or volatile
→ Filters by year, month, or custom date range
→ Works for any country — no hardcoded currency

────────────────────────────────────────

Important Note

These extensions work only inside the Manager.io environment using the built-in Extensions feature. They are not standalone apps.

How to add an extension in Manager.io:

1. Open Settings

2. Click Extensions

3. Click New Extension

4. Enter a Name

5. Set Source = URL

6. Paste the extension link into Endpoint

7. Choose a Placement (example: /)

8. Click Create

This matches the setup shown in the screenshots as below

────────────────────────────────────────

Both extensions are:

-> Free and open-source
→ Read-only — they never write, edit, or delete your data
→ Self-contained single HTML files — nothing to install

────────────────────────────────────────

I would really appreciate if you could:

-– Install and test either extension in your Manager.io
— Share what worked well or what did not
— Suggest features you would find useful
— Report any bugs or issues

All feedback is welcome, good or bad. Thank you for your time!
