Problem
Code review tools struggle to render large diffs efficiently, causing sluggish navigation, high memory usage, and degraded review experiences. As pull requests grow—especially those generated by AI agents—reviewers face performance bottlenecks that force teams to build workarounds instead of focusing on the actual review workflow.
Solution
Pierre Computer Company produces low-level, composable product infrastructure for machine work, starting with the Diffs component library. The library includes CodeView, a virtualization-first component for reviewing code and diffs that treats rendering, memory, and processing as connected problems. CodeView uses advanced virtualization to keep the DOM small, moves syntax highlighting into worker threads, and manages entire review surfaces at scale. The company also operates DiffsHub, a public playground where users can replace "github" with "diffshub" in a URL to virtualize nearly any public GitHub diff nearly instantly. Additionally, the company has released Highlights, a syntax highlighter written in WebAssembly Text that supports over 70 languages and generates HTML at up to 298× Shiki's throughput across large-file benchmarks.
Target Audience
Primary customers are product teams building code review tools, developer platforms, and AI agent workflows that need scalable, embeddable diff and code rendering infrastructure.
