Ktor vs Spring Boot: source lines of code compared

This page compares the source lines of code (SLOC) of ktorio/ktor and spring-projects/spring-boot 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, ktorio/ktor contains 197,512 total lines (115,169 code) across 1,945 files, while spring-projects/spring-boot contains 445,883 total lines (244,527 code) across 4,906 files as of 2026-08-26. spring-projects/spring-boot is about 2.1x the size of ktorio/ktor 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 ktorio/ktor: Kotlin (91.2% of code), JSON (3.2% of code), C Header (2.7% of code). Top languages in spring-projects/spring-boot: Java (87.0% of code), JSON (5.0% of code), JavaScript (3.5% of code). JSON, YAML appear in both top language lists; Kotlin, C Header, Rust appear only in ktorio/ktor's top languages; Java, JavaScript, XML appear only in spring-projects/spring-boot's top languages.

Methodology: both counts come from cached OctoCounts reports generated with tokei. ktorio/ktor was counted at ref main (commit 127a09a20267) on 2026-08-26; spring-projects/spring-boot was counted at ref main (commit 293c56bf5242) on 2026-08-26. 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, ktorio/ktor or spring-projects/spring-boot?

spring-projects/spring-boot has more code: 244,527 code lines versus 115,169 for ktorio/ktor, about 2.1x as much, based on cached OctoCounts reports as of 2026-08-26.

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 ktorio/ktor, spring-projects/spring-boot, or any repository.
