Zero-downtime deployment with Flagsmith and CircleCI

As developers, we continually strive to improve our software. This often means rolling out new software features at a rapid pace. However, deploying new features to production is not without risk. From no real production testing to limited rollback options, traditional deployment can quickly become frustrating. The worst issues, though, usually stem from one thing: buggy features making their way into the hands of users.

The strategic art of build vs. buy in software delivery ft. Tara Hernandez of MongoDB

Rob Zuber sits down with Tara Hernandez, VP of Developer Productivity at MongoDB and former Netscape engineer who helped create early continuous integration systems, to explore strategic frameworks for build vs. buy decisions in modern software delivery.

Set up preview deployments for pull requests using CircleCI and Vercel

Working in front-end development involves writing features and bug fixes in different branches. But how do you ensure that reviewers, testers, and other stakeholders find it easy to view changes? Using preview deployments is one solution. Preview deployments allow you to automatically create a live URL each time someone opens a pull request (PR). It’s like giving every branch its mini website so that changes can be tested and proven in isolation.

Platform Team Toolkit: Governance that accelerates developer velocity

Platform engineering teams face a critical challenge: scaling software delivery across dozens of development teams without killing innovation and velocity. The traditional approach forces an impossible choice: rigid standardization or operational chaos. Platform teams get buried in manual configuration requests, security updates take weeks to roll out, and compliance gaps emerge from inconsistent practices and developer workarounds.

Zero downtime deployments to Render using CircleCI

Downtime during deployments can affect the performance of your work. Data can be lost, and trust in your application can be destroyed. Luckily, zero downtime deployments do not need to be complex or involve a big infrastructure. This tutorial will teach you to establish a stable CI/CD pipeline with CircleCI and Render to automatically test and deploy a basic React application.

Platform Team Toolkit demo

Platform teams face an impossible choice: rigid standardization that slows developers down, or operational chaos that creates security gaps. CircleCI's new Platform Team Toolkit eliminates this tradeoff by delivering self-service developer experiences with built-in governance. What You'll See in This Demo: Key Benefits: Perfect for platform engineers, DevOps teams, and engineering leaders who need to scale software delivery without sacrificing speed or safety.

Looking beyond dev productivity to increase speed ft. Brian Guthrie of Justworks

Speed isn't just about developer productivity—it's about market dominance. Rob sits down with Brian Guthrie, Director of Engineering at Justworks and former ThoughtWorks consultant, to explore why lead time from conception to production should be your organization's north star metric.

Playwright fixtures: A deep dive

Fixtures may be one of Playwright’s most powerful yet under-used features. Playwright fixtures can be used to simplify repetitive setup or teardown in your tests, manage test data ,and test state better. Fixtures are key if your objective is to write cleaner, maintainable and manageable Playwright tests. This tutorial is aimed at helping you master using Playwright fixtures, understand their purpose, and showing how you can use them most effectively in your tests.

From painted doors to real prototypes - a mindset shift

The economics of building software are changing everything. For years, entrepreneurs used "painted doors" - fake features to test demand - because building was too expensive. But when AI drops development costs, you can create real prototypes and gather genuine user data instead of pretending. This mindset revolution treats experiments like cheap option contracts - the lower the cost, the more you can explore. Ready to abandon painted doors for unlimited experimentation?
