AI development agents aren’t just a cool bonus anymore — they’re becoming essential teammates in modern software workflows.

I’ve spent a lot of time testing, researching, and nerding out over the latest tools, and trust me: not all AI agents are built the same.
Some specialize in code completion, some in full-stack generation, some in supercharging your DevOps pipeline.

Here’s my 2025 must-know list if you want to stay ahead of the curve.
