JetBrains Developer Ecosystem 2026
Part 01

Tools and trends

Ten years of data-driven insights into developer tooling, leading programming languages, and the databases and clouds that keep everything running.

Section 1

Building software

The languages developers reach for, the ones they're eyeing next, and the kinds of software they’re creating.

Our language promise index

1.01

Now in its third year, the index combines five-year growth, adoption intent, and user loyalty to show how strongly each language is positioned for expansion in the year ahead.

A decade of language evolution

1.02

Looking back over the past decade, our language index highlights a clear trend: TypeScript, Python, and Rust have all grown considerably in popularity.

Five stories in the data

The foundational pillars – JavaScript, HTML/CSS, SQL and Java – all peaked around 2019–2020 and have steadily drifted downward since.

Top five languages developers want to adopt next

Everything talks to everything

1.04

Applications are increasingly integrating with APIs, services, and AI, reflecting the growing interconnectedness of software development.

Half of developers now integrate external APIs and services, and 45% build and provide their own. AI integration has reached 36%, making it more common than data processing and analytics.

Section 2

Running software

Where all that code actually lives: the databases, clouds, and platforms holding it up.

PostgreSQL pulls away

2.01

Last year, it was a photo finish. In 2026, PostgreSQL is clear of the field.

Evolution of database usage since 2019

0

Database usage in 2026

PostgreSQL gained 9 percentage points in a year to reach 59%, while MySQL held roughly flat at 54%.

Supabase and Firebase – backend platforms for building applications – are especially popular among developers with 2 or fewer years of experience. Other databases are more common among developers with 10+ years of experience.

A crowded sky

2.02

Cloud usage

AWS still holds the largest slice of the sky at 39%, but there's far more traffic up there than before.

Google Cloud (23%) and Microsoft Azure (21%) occupy the chasing positions.

Regional providers maintain strong footholds in their home markets: Alibaba Cloud and Tencent Cloud in China, Hetzner in Germany, OVHcloud in France, and Yandex Cloud in Eastern Europe.
