PacketLens
PacketLens is a pure front-end, offline pcap analysis tool that runs entirely in the browser, supporting deep protocol decoding, HTTPS decryption, and million-packet instant loading without any backend.
browser-automation-benchmark-v2026
A repeatable benchmark harness that compares Python Playwright, Rust playwright-rs, and Rust chromiumoxide on speed, memory, reliability, and startup time using synthetic and real-world fixtures.

FR-AI / ANALYSISWhy it is worth attention
It provides a unified, reproducible framework for comparing browser automation backends across two languages, with controlled warmup and interleaved runs to reduce measurement noise.
Who it is for
- Developers evaluating browser automation stacks
- Researchers studying performance of headless browsers
- Web scraping engineers comparing Python vs Rust
- Tooling maintainers looking for reliable benchmarking methodology
Use cases
- Comparing execution speed of Playwright in Python vs Rust
- Measuring memory consumption of chromiumoxide vs playwright-rs
- Assessing browser startup time under different runtimes
- Validating reliability of automation backends over repeated runs
Strengths
- Measures four key metrics (speed, memory, reliability, startup time) under a common harness
- Uses interleaved execution and warmup handling to improve consistency across sessions
- Supports both synthetic HTML fixtures and real Google Maps captures
- Saves raw run records alongside aggregated statistics for detailed analysis
Considerations
- Only supports Chromium-based browsers (no Firefox or WebKit)
- Requires both a Python environment and a Rust toolchain, increasing setup complexity
- Limited to three backends: Python Playwright, Rust playwright-rs, and Rust chromiumoxide
