Codespaces has a number of new features to get you coding fast, from anywhere on the web, with a single click. Let's jump right in!

You can now add recommended secrets to a project when creating a Codespace!

Recommending secrets will ensure developers won't miss any API keys when creating a Codespace from your repo. You can specify any secrets you need to run your project in a Dev Container. If a developer already has a secret stored in their user secrets, Codespaces recommends they add the secret to their repository. Developers can worry less about setup and jump right into development!

Do you want to share your project for others to try out? You can generate a share link to share in a tweet, add to your website, or send to a friend.

Want developers to pick up on the last Codespace they had when they clicked your share link? You can set your share links to drop developers into the same Codespace every time by selecting "Quick start."

You can select a specific Dev Container for the share link to create a codespace from! Codespaces detects the repo and branch from your repository, limiting your setup.

We've even made it easier to embed the share link into a nice "Codespaces" badge with HTML and Markdown. Nifty!

If your users have never created a codespace from your share link, they are recommended to create a codespace. If users already have a codespace from your share link, they are be prompted to resume their codespace.

Would a Dev Container by any other name smell as sweet?

You can now name your Dev Containers! By defining the property name in your devcontainer.json, you can set the name that will appear under the Dev Container selection on the Codespaces creation page. Even if you don't define the name property in your devcontainer.json, Codespaces will still infer a more useful name from your Dev Container file path.

Jumping Into Development From A Repository With A Comma

Do you want to collaborate on a repository, PR, or Branch? You can jump right back into your Codespace with the ',' key. No need to go to, or go to your Code<> drop-down to jump into development. Just one button and you're back to developing!

When editing a file on, repo admins, actors with the bypass branch protections permissions, and actors in bypass lists on branch protections will now default to creating a new branch instead for directly committing. You can still commit directly to a protected branch, but doing so will add notifications in-line highlighting that some rules will be bypassed.

Historically the default behavior was to push through any branch protections with no notifications they were being bypassed.

Now we recommend creating a branch for admins eligible to bypass branch protection rules. This behavior occurs when adding new files to a repository as well as during pull requests.
