When Chrome Ate My RAM: Designing a Pressure-Aware Tab Orchestrator with Rust
Summary

The article details a Chrome MV3 extension paired with a Rust native host via Native Messaging to manage tab lifecycles. The Rust pressure engine scores system state (RAM, CPU, battery) while focus clustering adjusts TTLs based on active workflow context. Strict guardrails—including never discarding active/pinned/audible tabs and enforcing cooldowns—ensure deterministic, non-disruptive behavior.

Key Takeaway

Implement a split-architecture pattern for browser tooling, delegating system metrics to a native host and browser lifecycle to an extension, with explicit guardrails to preserve user intent.

Why it matters

As a senior engineer focused on developer tooling and infrastructure, this demonstrates a pragmatic hybrid architecture (browser extension + native host) for building deterministic, context-aware system tools without cloud dependencies.
