k6 vs JMeter vs Gatling in 2026 — which would you choose for a new project?

Starting a new performance testing initiative. Our stack: Node.js microservices, REST APIs, ~50k requests/day in production. I've narrowed to these three: - **k6**: JavaScript scripting, good CI integration, Grafana Cloud integration, free OSS - **JMeter**: team has experience, GUI is useful for non-engineers, massive plugin ecosystem - **Gatling**: Scala DSL is powerful but steep learning curve for a Python/JS team Key requirements: must run in GitHub Actions CI, must produce threshold-based pass/fail results, nice to have good reporting. What would you pick and why?
