The MCP server and sem-ai are coming to Semaphore open source. Version 1.6 arrives exactly one year after 1.5 and packages up around 494 pull requests of new capabilities, built over the past year and now shared with the community. What Shipped MCP server in the open source editions The MCP server is now included […] The post Semaphore Open Source 1.6: MCP Server, sem-ai Out of the Box, and Partial Job Reruns appeared first on Semaphore.
AI coding agents work best when they receive the right information without unnecessary noise. They also need clearly defined permissions and reliable safeguards for the changes they make. sem-ai 0.4.0 improves all three areas. The release introduces more compact pipeline responses, flexible context switching, and support for Semaphore pre-flight checks. Watch Nick demonstrate the new […] The post sem-ai 0.4.0: smaller responses, safer access, and pre-flight checks appeared first on Semaphore.

AI agents can generate and modify code quickly. But when a test fails, speed is no longer enough. The agent needs enough context to understand what happened, why it happened, and whether the code or the test itself needs to change. In our latest product update, Marko Gaćeša is joined by Semaphore engineers Nick and […] The post Making testing work better for AI driven development appeared first on Semaphore.
Your pipeline fails on one job, and until now you had to rebuild the entire block to recover. Not anymore. Semaphore now reruns only the jobs that actually failed, so you get feedback faster and pay less to get it. What Shipped: Job Rerun When a pipeline failed, the old behavior rebuilt every job inside […] The post Rerun Only the Jobs That Failed appeared first on Semaphore.
MacOS Xcode16 reached the end of its supported lifecycle on Semaphore. To ensure the security, reliability, and maintainability of our platform, we are announcing the deprecation and end of life of MacOS Xcode16 build environments. Semaphore users should switch to Xcode26. Why We’re Deprecating Xcode16 As operating systems age, they cease to receive timely security […] The post Announcement: Xcode16 Deprecation in Semaphore appeared first on Semaphore.
Teams looking for CircleCI alternatives are rarely replacing a single feature. They are reassessing build speed, unit economics, support coverage, deployment control, and how easily their CI/CD system fits the source-control platform they already use. CircleCI remains a capable hosted CI/CD product, but its credit-based model meters active users, compute by resource class and minute, […] The post Best CircleCI alternatives in 2026 appeared first on Semaphore.
GitLab is a capable, integrated DevSecOps platform—but it is not the only sensible way to run CI/CD. Teams comparing GitLab alternatives are often trying to improve pipeline execution, simplify operations, get clearer support and cost options, or adopt a CI/CD tool that fits their existing source-control strategy. That does not automatically mean moving repositories out […] The post Best GitLab Alternatives in 2026 appeared first on Semaphore.
Bitbucket Pipelines is a logical starting point for teams already using Bitbucket Cloud. It is built into the source-control experience, configured in a bitbucket-pipelines.yml file, and offers both Atlassian-hosted execution and self-hosted runners. But convenience at the repository level is not always the same thing as the best long-term CI/CD operating model. Teams evaluating Bitbucket […] The post Best Bitbucket Alternatives in 2026 appeared first on Semaphore.
CI optimization is easiest to reason about when the problem is concrete: one pipeline, one critical path, and one cost model. Lawmatics reached out to us with that kind of problem. Their application pipeline was already parallelized and already using a sensible CI structure. The remaining question was whether the most expensive part of the […] The post How Lawmatics Cut CI Compute Cost by 39.3% and Shortened Pipeline Time by 15.8% appeared first on Semaphore.
Jenkins earned its place as the default CI server of the 2010s: it was free, endlessly extensible, and available before any serious managed CI/CD competitor existed. More than a decade later, that same flexibility has become the thing teams complain about most — plugin sprawl, Groovy pipeline scripts nobody wants to maintain, and infrastructure that […] The post Best Jenkins Alternatives in 2026 appeared first on Semaphore.
GitHub Actions became the default CI/CD choice for millions of repositories simply because it’s built into GitHub. But “default” and “best” are not the same thing — and in 2026, the gap between the two has gotten harder to ignore. A ten-hour outage in July, a supply-chain attack that backdoored over 5,500 repositories in May, […] The post Best GitHub Actions Alternatives in 2026 appeared first on Semaphore.
Choosing a CI/CD tool in 2026 isn’t just a technical decision — it’s a cost and productivity decision. Slow pipelines mean slower shipping, and opaque pricing means budget surprises at the end of the month. We benchmarked five of the most widely used CI/CD platforms against the same workload: a real Ruby on Rails application […] The post Best CI/CD Tools in 2026: Performance and Cost Compared appeared first on Semaphore.
You can now identify your flakiest tests through the API and have an AI agent fix them, at a cost of around $1 to $1.50 per fix. What Shipped Flaky Test Data in the API (Generally Available) Flaky test data is now accessible programmatically through the sem-ai API. The API surfaces tests ranked by disruption […] The post Flaky Test API Now GA, New Auto-Fix Skill, Skill Quality Improvements appeared first on Semaphore.
sem-ai keeps moving. Here’s a quick rundown of what shipped last week and what’s coming next. What Shipped on Sem-AI Glitches have been fixed.A few issues were blocking some users to get started with sem-ai. Those are resolved. If you tried it before and ran into friction, now’s a good time to try again. See […] The post Codex Support, Faster Task Creation, and Flaky Test Visibility appeared first on Semaphore.
Developers don’t want to spend their time writing CI configuration, debugging flaky pipelines, or digging through logs to understand why a build failed. They want to ship software. That’s the idea behind sem-ai – Semaphore’s approach to building an AI-native CI experience where developers interact with CI/CD using natural language, directly from the tools they […] The post Building an AI-Native CI/CD Experience with sem-ai appeared first on Semaphore.
MacOS Xcode15 reached the end of its supported lifecycle on Semaphore. To ensure the security, reliability, and maintainability of our platform, we are announcing the deprecation and end of life of MacOS Xcode15 build environments.

Embedded and IoT teams face a very different CI/CD reality than traditional SaaS teams. While most continuous integration and continuous delivery pipelines assume everything can run in the cloud, embedded systems depend on physical hardware, constrained environments, and real world signals. If you search forums like Reddit (r/embedded, r/devops), Stack Overflow, or vendor communities, the […] The post What CI/CD strategies work for embedded or IoT projects that require hardware testing? appeared first on Semaphore.
