The State of Developer Ecosystem in 2025

JetBrains' 2025 Developer Ecosystem Report reveals key trends in programming languages, tools, and platforms. Python and Java maintain dominance while TypeScript shows dramatic growth over five years. Rust, Go, and Kotlin continue steady adoption, while PHP, Ruby, and Objective-C decline. Most developers build integrations between systems rather than standalone applications, with AI embedding now as common as data processing. Three-quarters of developers focus on web and business software. AWS leads cloud platforms with the largest market share, while PostgreSQL has overtaken MySQL as the most popular database.
