GitLab Transcend Hackathon: What developers built on GitLab Orbit
We gave a few thousand developers GitLab Orbit. Then we got out of the way. The community responded with creative solutions to real production problems slowing down their teams. The same problems you hit every week: What does this change break, which tests actually matter, and what will this migrati...
Use OpenTelemetry-native observability with Datadog from ingestion to investigation
Learn how you can use vendor-neutral telemetry while preserving Datadog’s infrastructure and APM experiences.
The cost of saying yes has changed
The cost of writing code dropped; the cost of owning it didn't. A framework for deciding which changes are actually cheap in the AI era. The post The cost of saying yes has changed appeared first on The GitHub Blog .
Eclipse Dataspace Components on AWS: Cost optimization strategies
When you deploy Eclipse Dataspace Components (EDC) connectors on AWS, one of the first challenges you face is predicting and controlling the cost of the required infrastructure. Without clear benchmarks, it is difficult to make informed decisions about workload sizing, environment configuration, and...
Eclipse Dataspace Components on AWS: Architecture patterns in production
Running Eclipse Dataspace Components (EDC) connectors in production on AWS requires deliberate architecture decisions around isolation, managed services, and security layering. In Part 1 of this series, we covered the fundamentals of data space architectures and EDC per the International Data Space ...

Prioritize your AWS Health alerts using AWS User Notifications
If you run critical workloads on AWS, such as a contact center on Amazon Connect Customer, database workloads on Amazon Relational Database Service (Amazon RDS), or hybrid connectivity through AWS Direct Connect, service health events demand your attention. But not all events are equal. An operation...
Turn multi-step software delivery into agentic flows you can trust
Knowing what to do next in software development is rarely the hard part. Doing it again in the exact same steps — implement an issue, fix a pipeline, review a merge request — is. Chat that only provides answers still leaves every handoff to you. Homegrown scripts don’t inherit changes in access cont...
GitLab Duo Security Review spots logic flaws scanners miss
Static scanners excel at catching vulnerabilities that fit a known pattern, like unsanitized query inputs, hardcoded secrets, and unsafe deserialization. They struggle against flaws in your application’s logic, where there is no pattern to match — only valid code doing the wrong thing for your domai...
Bring GitLab Duo Agent Platform to your terminal
Most of the work for software delivery doesn’t happen only in the editor. Pipelines fail. Tests break. Vulnerabilities show up. And a lot of that work starts and ends at the command line. Agentic AI in the terminal that only understands code can’t help with any of that. A standalone assistant doesn’...
Forrester Consulting: GitLab Duo Agent Platform delivers 400% ROI
A new Forrester Consulting Total Economic Impact™ study found that organizations using GitLab Duo Agent Platform achieve a 400% return on investment and $7.5 million in net present value over three years — with payback in under six months. Agentic coding makes developers faster. The harder problem i...

When a version bump breaks your build, GitLab fixes it
AI is writing more code and pulling in more dependencies, increasing application risk. Most of that exposure isn't from code your team actively chose. A 2025 study of the Maven ecosystem found vulnerabilities reaching roughly 63% of latest releases through transitive dependencies, versus 31% through...

How bitdrift scaled to 121 million concurrent gRPC connections on Amazon CloudFront for live telemetry sporting events
When 121 million mobile devices establish persistent gRPC connections to your origin infrastructure within seconds of a live broadcast, the routing policy behind your DNS records matters far more than it does at normal traffic levels. The wrong policy can concentrate all your connections onto a sing...
