Every time you deploy to Firebase hosting a new deploy version is created so you can roll back and see who deployed. This means that each time every file you deploy is stored and occupying more space.

Other than manually deleting each deployed version one by one, is there any automated way to clean those useless files?

You're correct. You'll need to delete the old deployed versions one by one using the Firebase Hosting console.

There's no other way to do this, so I'd suggest you to file a feature request to enable deletion of multiple deployed version in the Firebase Hosting console.

The name of the version to be deleted, in the format: sites/ site-​name /versions/ versionID  Instead, you should change the index.html on your local copy where you initially ran the firebase deploy command. Once you're done with the changes, run firebase deploy again to push the updated version of your website to Firebase Hosting. For small changes it is probably faster to run firebase serve. This spins up a local web server, so that you can test the changes.

UPDATE Mar/2019

There's now a proper solution: "Version history settings" which allows to keep the last X versions.

UPDATE Feb/2019

Confirmed by Google employee @

It is actively being worked on. 🙂

So, by using Chrome Dev tools I found a way to delete multiple versions. Keep in mind it requires a bit for work (proceed with care since deleted versions can't be restored and you won't get any warnings like when using the UI).

Step 1. Retrieving the version list.
  1. Open Chrome Dev Tools (if you don't know how to chances are you should wait for a proper solution by Firebase's team).
  2. Open Firebase's Console and go to the "Hosting" tab.
  3. Go to the "Network" tab on CDT and use the Websockets filter.
  4. Select the request named .ws?v=5&ns=firebase
  5. Open the "Frames" tab
  6. Now comes the tedious part: Select the frames with the highest "length" value. (Depending on your data, it could be 2-n frames. In my case, 3 frames with 14k-16k length)
  7. Paste each of the frame's data in order (which will form a valid JSON object).
  8. Extracting the data: There are several ways to do it. I opted for simple JS on CDT's console.
    var jsonString = '...';
    var json = JSON.parse(jsonString);
    var ids = Object.keys(json.d.b.d);
Step 2. Performing the requests

Almost there :P

Now that you have the IDs, perform the following requests:


I used Sublime (to create the request strings) + Paw.

The "KEY" can be copied from any of CDT's requests. It doesn't match Firebase's Web API key

=> Before performing the requests: take note of the version you don't want to delete from the table provided by Firebase. (Each version listed on the website has the last 6 digits of it's ID under your email)

(Screenshots weren't provided since all of them would require blurring and a bit of work)

Method: sites.versions.delete, Parameters and conditions · Templates and versioning · Config loading strategies Define your Firebase Hosting configuration in your firebase.json file. You can check the deployed firebase.json content using the Hosting REST API. When false , Hosting redirects URLs to remove a trailing slash.

Versions that are already deployed will be updated during August. July 27, 2018 SDK Releases. The Firebase Android SDK for Cloud Firestore has been updated.

This may be a bit brittle due to the selectors' reliance on current DOM structure and classes on the Hosting Dashboard, but it works for me!

NOTE: This script (if executed from the console) or bookmarklet will click and confirm delete on all of the rows in the current view. I'm fairly certain that even if you click delete on the current deployment it will not delete it.

Function for running in console:

let deleteAllHistory = () => {
  let deleteBtns = document.querySelectorAll('.table-row-actions');

  const deleteBtn = (pointer) => {

        setTimeout(() => {
          document.querySelector(' md-menu-item:last-child button').click();

          setTimeout(() => {
            document.querySelector('.fb-dialog-actions .md-raised').click();

            if(pointer < deleteBtns.length - 1) {
              deleteBtn(pointer + 1);
          }, 500);

  • This is now the answer as of March 2019:
  • I've filled a feature request, but I doubt it will be implemented. Oh well.
  • Oh, the agony -- in my case, I have 218 of them! (click menu, click delete, click delete... click menu, click delete, click delete... repeat 218 times...)
  • @Pier Please link to the feature request you created so we can track it. Thanks! Edit: I see feature requests on firebase are not public. Thats kind of...not great.
  • @Levi It was also reported on the firebase-tools repo. To everyone: You can vote here (please avoid +1 spam, use reactions)… for one of the alternatives proposed by the team (batch delete, keep only X versions, keep versions with published date < Y)
  • This cleared 3GB of old deployments in a matter of five minutes. Thank you!
  • Cool! you make my life easier.
  • I've made it to the last step, except I wanted to use the in-browser tools to send the DELETE requests. This seems to be correct: fetch(`${projectID}/versions/${versionID}?key=${key}`, {method: "DELETE", credentials: 'include'}); However, on running, it says "Request is missing required authentication credential." It's odd because the Network tab shows the requests as being identical. (other than tiny variations in two of the cookies, which seem unrelated)
  • @Venryx you figure that out?
  • No, sorry. I ended up using @AAverin's solution above, which works fine.
  • Awesome. This should now be the answer.
  • beware this will delete the domain :|
  • You should put relevant code/instructions here in order to avoid any future broken link making you answer useless.
  • Yes, but you have to do it manually. One by one. Did you even read the question?
