1. Official GitHub Slack integrations.

Since this is an official integration there are cool features you will not see in another type of reminder bots, such as displaying code directly in Slack.

😍 What we like:

Code can be displayed directly in Slack. It's highly customizable, you can choose which repository you can subscribe to, deactivate some notifications. The integration is well documented. It's also maintained by the GitHub team, and if you have questions you might be able to ask them directly.

Axolo has more than 1k installations on the official GitHub marketplace and offers a free tier.

🤔 What we don't like:

It takes time to set it up and can be confusing as well. In order to have it work, you will need to subscribe manually to each of the repositories using Slack slash commands.

2. Axolo: improving the developer experience

Focusing on collaboration across the whole engineering team, Axolo is not another pull request notification bot. It is engineered to optimize code review and streamline the pull request resolution process by fostering collaboration across the entire engineering team. The platform is designed to enable seamless discussions about code, ensuring that all team members have access to the information and tools they need to resolve pull requests efficiently.

😍 What we like:

Axolo makes a temporary Slack channel for every GitHub pull request, it will invite reviewers and assignees to the channel, notify them of relevant events like code comments, comments, GitHub Actions, Deployments and finally it will archive the channel once you close or merge pull request.

🤔 Improvements:

Some teams have shared that it used to be too noisy. The Axolo team introduced code reviewing timeslots in September 2021. Developers can choose the time in the day when they want to be invited to review a new pull request. It's a good way to keep the focus on coding and having dedicated time for code reviews during the day.

✨ Features:

💭 An ephemeral Slack channel for each 1 PR = 1 channel

Axolo enhances your slack integration with github by creating an ephemeral slack channel for every pull request.

What are the benefits of GitHub Slack integration?

Imagine you're deep in the zone, writing code that's going to change the world—or at least fix that one annoying bug—and then you have to stop to check GitHub for a pull request. Context-switching is the top enemy of productivity for developers. Integrating GitHub with Slack keeps you in the loop without breaking your flow.

Here's why GitHub Slack integration is a game-changer for developers:

• Real-Time Notifications: Get instant updates on pull requests, code reviews, and issues directly in Slack. No more refreshing GitHub pages.
• Reduced Context Switching: Stay focused on your code. Important GitHub events come to you in Slack, so you don't have to juggle multiple platforms.
• Streamlined Code Reviews: Discuss code snippets and review comments right within Slack channels or threads. Keep the conversation and the code together.
• Faster Collaboration: Quickly loop in team members by mentioning them in Slack, accelerating problem-solving and decision-making.
• Automated Workflows: Approve pull requests, merge code, or trigger CI/CD pipelines from Slack commands. Automate repetitive tasks to save time.
• Enhanced Visibility: Keep track of project progress with Slack notifications about deployments, builds, and test results.
• Customized Alerts: Tailor notifications to your needs. Subscribe to specific repositories or mute less critical updates.

By bringing GitHub into Slack, you create a centralized hub for both communication and code collaboration. This integration not only boosts your productivity but also enhances team synergy, making the development process more efficient and enjoyable.

Conclusion

We looked at 5 different GitHub and Slack integrations. Those 5 integrations take a different approach in trying to make pull requests last shorter.

We see two types of GitHub and Slack integrations:

1. The one that are simple notifications based on events:

Those bots, like Toast.ninja, the official GitHub Slack integration will notify either you personally or a channel that a Pull Request is ready to be reviewed.

Downside:

One place for all pull requests notifications is good for smaller teams but can become a nightmare for larger teams. It can easily be ignored after a while.

2. The truly collaborative apps:

Axolo is the best in this category. On top of enabling the right notifications (like CI/CD, GitHub actions, deployment and checks), Axolo creates contextual channels for each Pull Request.

Companies that use Axolo found that creating those spaces to talk about a specific pull request makes it easier to collaborate during code reviews, improve the developer experience and resolve pull requests quickly.
