Glimpse is a tool that automates GitHub pull request previews for Laravel projects using Laravel Forge, ensuring quick and accurate testing environments. Developers can create isolated environments for every pull request, allowing for thorough testing before merging code. The automatic creation and decommissioning of environments ensure efficient resource usage and easier project management. Glimpse integrates with popular tools like GitHub, Slack, and Linear, improving collaboration and communication during the development process. Teams can also customize deployment scripts and manage environment variables for each preview. With Glimpse, Laravel developers can enhance their workflow by focusing on coding instead of manual setup.
