   Calls Junie really good, but JetBrains restricts it to a curated list of model variants without support for arbitrary OpenAI-compatible endpoints. Its AI strategy has pivoted too often.

   Prompts, pitfalls, and progress: What I learned building an app with AI agentsCompany engineering blog post, Equal Experts

   An Equal Experts engineer built a full app through agents without writing code. He started with Junie and found it well integrated with the IDE, but moved to Warp's terminal workflow, and agents often ignored his .junie/guidelines.md rules.

   "…while Junie was great and nicely integrated with the IDE. I ended up preferring the workflow from the terminal as offered by Warp and Amazon Q."

   "Despite setting up a .junie/guidelines.md with explicit instructions (like always updating prompts.txt), agents often ignored them or followed them inconsistently."

   Junie in IntelliJ was what convinced them AI coding was the future. They later ran Junie CLI in parallel with other agents but dropped it because instruction compliance broke down on their workflows.

   My experience using Junie for the past few monthsPersonal blog post, lengrand.fr (Julien's DevRel corner)

   Calls Junie one of the best coding agents tried so far, very well integrated with IntelliJ, great for Kotlin and good thanks to its test-first focus. But it is very eager to do more than asked, extremely slow (between 3 and 4 minutes on simple-ish requests), and cannot accept part of a solution.

   Radchenko reports that Effective used Junie to speed up an internal meeting-room booking app with a Spring Boot backend and Kotlin Multiplatform client, estimating, "in my opinion", about a 30% speed-up and up to 50%. Junie wrote roughly 70/30 of backend code, the reverse on the KMP client, and sometimes looped in complex scenarios.
