Embed our free tree tools on your site
Give your visitors a working tree height calculator, a tree picker or a state data badge. Copy the code, paste it into your page, and keep the small credit link. Free, no sign-up.
How it works
1. Pick a tool or a state
Each tool below has its own code. State badges are further down.
2. Copy the code
Press the copy button. The code is an iframe plus one line with a credit link.
3. Paste it into your page
Use your site builder's HTML or custom code block. Change the height if the tool needs more room.
What ?embed=1 does
Every tool link works on its own. Add ?embed=1 to the end, for example https://lirevon.com/tools/tree-height-calculator?embed=1, and the page hides our header, footer, menus and share bar. Only the tool shows, with a small "Powered by Lirevon" line at the bottom. The codes below already include it.

Common questions
Is it free to embed your tools?
Yes. There is no fee, no sign-up and no key. Copy the code, paste it into your page and keep the credit link under it.
What does ?embed=1 do?
It is a switch at the end of the tool link. When it is there, the page hides our header, footer, menus and share bar, so only the tool shows inside your page, with a small "Powered by Lirevon" line at the bottom.
Will the tool send my visitors' numbers to you?
No. The tools run in the visitor's own browser. What they type is not sent to us or to you. Some tools remember inputs on that device only, so the visitor can come back to them.
Can I change the height of the embed?
Yes. Change the height number in the code. 900 pixels is a starting point; long tools and checklists may need more. The width is set to 100% so it fits your page on any screen.
Do I have to keep the credit link?
We ask you to. The credit link tells your visitors where the tool comes from and lets them find the full version. It is the only thing we ask for.
Where do the numbers in the state badges come from?
From our own check of tree companies on Google Maps, finished October 26, 2026. We counted companies, checked for a website, and checked those websites for a way to text the business. The badge links to the full state report, which explains the method.
Will the badge numbers change?
Only if we run a new check. When we do, the badge updates on its own because it loads from our site. The month of the check is shown on the badge.
Can I embed a tool on a tree service company website?
Yes. Homeowner tools like the tree height calculator, the tree picker and the hiring checklist work well on a tree company's own site. Results are estimates, and the tool says so.
Can I use the data in my own article instead of a badge?
Yes. Our open data page has CSV downloads under a CC BY 4.0 licence. Quote the numbers, credit Lirevon and link to the source page.
What if an embed looks broken on my site?
Email hello@lirevon.com with the page link and what you see. Some site builders need the code pasted into an HTML or custom code block, not a normal text block.
