How to report a bug to Bolt (with a screenshot)

To report a bug to Bolt, attach a screenshot with the broken part marked using the plus icon in the chatbox, say which page it is on and what you expected, and paste any red console errors.

Updated

Bolt can look at a picture, so the fastest bug report is a screenshot and one clear sentence. The details below keep it from guessing which part you mean.

Step by step, by hand

  1. Make the bug happen once more. Note what you clicked, in order.
  2. Take a screenshot and mark the broken part. A red box tells Bolt which of the things on screen you mean. Crop to the area around it.
  3. Attach it. Click the plus icon in the bottom-left of the chatbox, then Attach file, or drag the file into the chatbox. Keep it under 5 MB and in PNG, JPG or WebP.
  4. Say what you expected. One sentence. "The price should update when I change the quantity, like it does on the product page."
  5. Say how far the fix should go. "Only this card" or "all cards".
  6. Add the clues a picture can't show. If nothing visible happens, open the browser console (Cmd+Option+J on a Mac, Ctrl+Shift+J on Windows) and paste the red lines. See how to copy console errors.

The one-key way with Darnly

Darnly is a free Chrome extension that makes the screenshot and the note together, on the Bolt preview or your published site. Press Option+Shift+B (Windows is coming soon), click the broken part, type what you expected and press Enter.

Then drag the bug from the Darnly panel into Bolt's chatbox, or click 1. Copy picture and 2. Copy details and paste each one. The picture has the broken part boxed in red with your note on it. The details hold the page address, the element's text and styles, and failed requests from the last 60 seconds, plus console errors if you switched on Record errors on this site. Passwords, card numbers, tokens and keys are hidden before anything leaves the panel.

Darnly doesn't make Bolt smarter. A good screenshot and sentence often get the same fix. What it saves is the hand-over. See Darnly vs a plain screenshot.

Questions

Why does Bolt reject my screenshot?

Bolt reads each attached file up to 5 MB and can't process images larger than about 16 megapixels. Crop the screenshot to the broken area, or save it as JPG or WebP.

Bolt reads SVG files as text, not as a picture. Use PNG, JPG or WebP when you want Bolt to look at it.

A screenshot with the broken part marked, the page it is on, what you did, what happened, what you expected, and any red console errors.

Is Darnly free?

Yes. The Chrome extension is free, and capturing and copying a bug needs no account.
