Telepresence streamlines your local development process, enabling immediate feedback. You can launch your local environment on your laptop, equipped with your preferred tools, while Telepresence seamlessly connects them to the microservices and test databases they rely on. It simplifies and expedites collaborative development, debugging, and testing within Kubernetes environments by establishing a seamless connection between your local machine and shared remote Kubernetes clusters. Why Telepresence: Faster feedback loops: Spend less time building, containerizing, and deploying code. Get immediate feedback on code changes by running your service in the cloud from your local machine. Shift testing left: Create a remote-to-local debugging experience. Catch bugs pre-production without the configuration headache of remote debugging. Deliver better, faster user experience: Get new features and applications into the hands of users faster and more frequently.

DebugBear keeps track of your site speed and Core Web Vitals. Monitor the performance of your website and benchmark against the competition. Get alerted in Slack or by email when there's a problem. DebugBear is built on top of Google's Lighthouse tool, but provides additional in-depth debug data for developers. It also keeps track of the real-user Core Web Vitals metrics that Google uses for their search rankings.

Reports arrive to you instantly, automatically supplemented with a ton of useful data so you can fix them 50X faster. Whenever users notice a bug, they just shake their phone to report it, without ever leaving your app. When they shake their device, Shake opens up and allows them to send you feedback without ever leaving your app. Report yourself any info from the user’s device you want. Use .setMetadata() to easily adjust the data to your debugging requirements. See the user’s taps around your app, .log() custom events and see all their network traffic prior to reporting the bug to you. On the web Dashboard you can, for example, effortlessly find only bugs reported from iPad Airs that were in landscape mode and offline. Get bug notifications immediately in your team chat. Or, have tasks created directly in your issue tracker of choice. Shake was built to play nicely with the tools your team already uses.

Defang is a developer-centric platform that simplifies the process of developing, deploying, and debugging cloud applications. By leveraging AI-assisted tooling, Defang enables developers to swiftly transition from an idea to a deployed application on their preferred cloud provider. The platform supports multiple programming languages, including Go, JavaScript, and Python, allowing developers to start with sample projects or generate project outlines using natural language prompts. With a single command, Defang builds and deploys applications, handling configurations for computing, storage, load balancing, networking, logging, and security. The Defang Command Line Interface (CLI) facilitates interactions with the platform, offering installation options via shell scripts, Homebrew, Winget, Nix, or direct download. Developers can define services using compose.yaml files, which Defang utilizes to deploy applications to the cloud.

Shoreline is the Cloud Reliability platform — the only platform that lets DevOps engineers build automations in an afternoon, and fix issues forever. Shoreline reduces on-call complexity by running across clouds, Kubernetes clusters, and VMs allowing operators to manage their entire fleet as if it were a single box. Debugging and repairing issues is easy with advanced tooling for your best SREs, automated runbooks for the broader team, and a platform that makes building automations 30X faster. Shoreline does the heavy lifting, setting up monitors and building repair scripts, so that customers only need to configure them for their environment. Shoreline’s modern “Operations at the Edge” architecture runs efficient agents in the background of all monitored hosts. Agents run as a DaemonSet on Kubernetes or an installed package on VMs (apt, yum). The Shoreline backend is hosted by Shoreline in AWS, or deployed in your AWS virtual private cloud.
