Performance & Benchmarks

By stripping away Webpack overhead, Virtual DOM reconciliation, and heavy language servers, Veyrix operates on a fraction of the hardware requirements of modern cloud IDEs.

Environment Base RAM (idle) Editor engine Time to interactive
Veyrix IDE ~30MB – 42MB Ace Editor (vanilla) < 0.5 seconds
VS Code Web ~350MB+ Monaco + Web Workers 2.5 – 4 seconds
CodeSandbox ~500MB+ Monaco + Container VM 4 – 8 seconds

Why it's better for mobile / low-end devices

  • Debounced I/O — IndexedDB writes are debounced by 500ms, ensuring zero main-thread blockage during rapid typing
  • No Monaco overhead — Monaco is powerful but struggles on low-end Androids due to heavy worker threading; Ace Editor is substantially lighter
  • Visual viewport anchoring — PWA implementations often suffer layout thrashing when the soft keyboard appears; Veyrix anchors directly to the window.visualViewport API, freezing the reflow

Error Handling Behavior

"Incognito" / Private Mode restraints

Safari and Firefox frequently restrict or completely block IndexedDB access in Private Browsing. If DB.init() fails, Veyrix degrades gracefully to an in-memory volatile state. A UI toast warns the user that files will be lost when the tab closes, prompting manual downloads.

DOMException: QuotaExceededError

Triggered when the device runs out of disk space, or the browser's origin quota is exceeded. Veyrix catches this in the DB.save() promise rejection, halting autosave and notifying the user to clear space or delete older snapshots.
