Semaphore Uncut

Flaky test data is now accessible through the sem-ai API, and this week also brings a skill that uses that data to fix the tests automatically. Flaky test data is now generally available through the API. You can query your flakiest tests programmatically, sorted by number of disruptions, with failure timestamps and logs included. Find it on github . A new sem-ai skill can identify and fix flaky te...

Here’s an update on what our engineering team has been shipping in sem-ai and what’s coming up next. Codex marketplace support is live. A few issues were blocking some users from getting sem-ai working on Codex. Those are now fixed. If you tried it before and hit a wall, it’s worth giving it another shot. Task creation got faster. We cleaned up some unnecessary API calls that were causing hiccups....

We’ve been talking a lot recently about AI-native developer workflows and where CICD is heading. This week, we shared one of our most exciting demos yet: a look at how SEMai is changing the way developers interact with CICD systems. In the demo, Marcos starts with a completely clean repository: no CI configuration, no GitHub Actions workflows, nothing. Then, inside Claude Code, he runs a single co...

Developers are increasingly working inside AI-powered coding tools like Claude Code, Cursor, and Codex. The workflow is changing. Instead of constantly switching between dashboards, logs, terminals, and configuration files, developers are starting to collaborate directly with coding agents using natural language. We think CI/CD should evolve alongside that shift. Today, we’re introducing Semaphore...

Modern development teams don’t all build on the same stack and they should not have to. Today, we are expanding Semaphore’s capabilities to better support teams building on the Microsoft ecosystem, with first class support for the .NET framework and Microsoft Edge in CI pipelines. This marks an important step toward making Semaphore a truly flexible platform for all developers, regardless of their...

As AI agents become part of everyday development workflows, authentication is becoming a critical piece of the puzzle. In our latest product update , we’re sharing a behind-the-scenes look at how we implemented OAuth for Semaphore’s MCP server—and what we learned along the way. You’ll get a practical perspective on: * Why OAuth is essential for MCP and AI agents * The challenges of working with ev...

Today we’re introducing an important change to how Semaphore pricing works. CICD is no longer something that runs occasionally during development. For many teams, it’s now always-on infrastructure that powers software delivery. To support this shift, we’re introducing a new Semaphore pricing model designed to keep CICD fast, scalable, and affordable as usage grows. What’s changing The new model se...

We’re preparing a new update for the Semaphore MCP server that will make it easier for developers to connect AI agents and developer tools. The focus of this update is authentication . Today, connecting an agent to the MCP server typically requires using a long-lived API token. While this works well, it also means developers need to generate credentials, store them in configuration files, and mana...

🚀 We’re introducing AI-driven onboarding and workflow automation in Semaphore. Our new assistive agent helps teams generate pipeline configurations, understand failed jobs, re-run workflows, and refine CI/CD setups using natural language — all while keeping developers fully in control. This is the beginning of Agent-Driven Semaphore: CI/CD at the core, AI handling the repetitive work. Watch to se...

Over the past few weeks, we’ve been refining our roadmap for 2026 and focusing on where Semaphore can deliver the most value. Our direction is clear: extend CI/CD beyond execution — and help developers ship software faster. Here’s what’s coming next. This is a public episode.

In this episode of Semaphore Uncut , Keren Fanan (CEO & Co-founder) and Hadar Geva (CTO & Co-founder) of MyOp share how years of building and scaling frontend systems led them to rethink how UI should be built, shipped, and managed in production. This conversation covers: * How frontend systems break down over time due to framework churn and legacy code * Why treating UI components as runtime cont...

AI agents can reason, but they don’t actually understand your systems. MCP servers fix that by giving your copilots and assistants structured access to your tools, APIs, and CI/CD data. And the best part is that building one is much simpler than most people expect. In the latest episode of Technical Tips , Tommy walks through how to create a functional MCP server in just a few minutes. He connects...

In this episode of Semaphore Uncut, Jonathan Reimer—founder of Crowd.dev and now VP of Outbound Products at the Linux Foundation—breaks down what he’s learned from years inside the open source startup ecosystem. This conversation covers: * How Crowd.dev grew into a core insights platform for OSS communities and was later acquired by the Linux Foundation * The three types of open source companies J...

In this episode of Technical Tips , Tommy shows you how to run tests across multiple environments without duplicating your CI/CD setup or writing repetitive jobs. He explains how job matrices in Semaphore help you expand test coverage, catch regressions early, and keep your pipelines organized and efficient.
