⚙️ How it works

PosSol is built entirely on Serverless Edge Functions using native SVG generation.

• Zero Dependencies: There are no heavy binaries or external charting libraries slowing it down.
• Auto-updating Cache: Charts are cached heavily at the Vercel edge (s-maxage=300), guaranteeing your profile loads instantly while keeping data perfectly fresh behind the scenes.
• Fail-safe Fallbacks: PosSol intelligently routes data between APIs to ensure 100% uptime for your profile.
