Spring Boot vs Quarkus: source lines of code compared

This page compares the source lines of code (SLOC) of spring-projects/spring-boot and quarkusio/quarkus using cached OctoCounts reports. Code size is not code quality: a larger count only means more source material, not a better or worse project.

As of 2026-08-26, spring-projects/spring-boot contains 445,883 total lines (244,527 code) across 4,906 files, while quarkusio/quarkus contains 1,258,293 total lines (939,141 code) across 15,242 files as of 2026-08-29. quarkusio/quarkus is about 3.8x the size of spring-projects/spring-boot by code lines. Code size is not code quality: a larger count only means more source material, not a better or worse project.

Top languages in spring-projects/spring-boot: Java (87.0% of code), JSON (5.0% of code), JavaScript (3.5% of code). Top languages in quarkusio/quarkus: Java (75.6% of code), XML (14.6% of code), JavaScript (4.4% of code). Java, JSON, JavaScript, XML appear in both top language lists; YAML appears only in spring-projects/spring-boot's top languages; Kotlin appears only in quarkusio/quarkus's top languages.

Methodology: both counts come from cached OctoCounts reports generated with tokei. spring-projects/spring-boot was counted at ref main (commit 293c56bf5242) on 2026-08-26; quarkusio/quarkus was counted at ref main (commit 5a34b6a26867) on 2026-08-29. See the counting methodology for ignored directories and analysis options.

Evidence and next steps:

Note: code size is not code quality. OctoCounts only reports reproducible line counts and makes no claim that either project is better.

Compare FAQ

Which has more lines of code, spring-projects/spring-boot or quarkusio/quarkus?

quarkusio/quarkus has more code: 939,141 code lines versus 244,527 for spring-projects/spring-boot, about 3.8x as much, based on cached OctoCounts reports as of 2026-08-29.

Does more source lines of code mean more complexity?

Not necessarily. SLOC measures size, not complexity, quality, or maintainability. A larger codebase can mean more features, more generated or vendored code, more verbose language idioms, or more tests — none of which imply the code is harder to work with. Use SLOC to gauge the scale of what you'd be reading or maintaining, not as a quality signal for spring-projects/spring-boot, quarkusio/quarkus, or any repository.

How is this comparison calculated?

Methodology: both counts come from cached OctoCounts reports generated with tokei. spring-projects/spring-boot was counted at ref main (commit 293c56bf5242) on 2026-08-26; quarkusio/quarkus was counted at ref main (commit 5a34b6a26867) on 2026-08-29. See the counting methodology for ignored directories and analysis options.
