AI Analysis

●●●BangerWizardryBig BrainZero to One

Zero-copy SHM beats Playwright's 2.3s capture loop with 7ms agent vision.

Strengths

•POSIX shared memory bypasses base64 serialization, cutting latency from seconds to milliseconds.
•Direct DOM compositor buffer access eliminates OCR and encoding overhead entirely.
•Hardened 4GB V8 memory cage allows running untrusted scraper code safely.

Weaknesses

•Forked from neural-chromium — not entirely original implementation.
•Linux/macOS focus with Windows support unclear for SHM-based architecture.

Post Description

We built an MCP server that uses SHM/DMA to pass DOM compositor buffers directly to agents, bypassing base64 screenshot serialization delays. Latency is ~7.35ms. We just migrated out of Beta and are granting 10K free frames to devs who authenticate. Check it out at https://glazyr.com!
