What is opencode-visual-cache?

This is a plugin for OpenCode that drops a real-time statistics panel into the sidebar, tracking token cache performance while you code. It shows cache hit rate with a visual progress bar, breaks down cache read/write/miss/output tokens, and calculates how much money you're saving from cache hits across a session. The panel also displays model pricing and token distribution by role (system prompts, user input, agent instructions, tool calls, tool results). Built in TypeScript using SolidJS for the TUI rendering.

Why is it gaining traction?

The killer feature is the cost visibility -- developers finally have a concrete way to see whether their cache strategy is actually paying off. The auto-desaturated color scheme is a thoughtful touch: it reads well in any terminal theme without clashing, and the hit rate color-codes automatically (green for good, red for bad). Bilingual support out of the box makes it accessible to international teams without extra configuration.

Who should use this?

OpenCode power users who run long coding sessions with expensive models like Claude or GPT. Cost-conscious developers evaluating cache efficiency. Teams analyzing token usage patterns across agents or workflows. Not useful outside of OpenCode -- this is a niche tool for a specific workflow.

Verdict

This is a small but polished utility solving a real pain point (Understanding what caching actually saves you). The 12 stars reflect early-stage status, and the lack of documented test coverage means treat it as community software. At 0.85% credibility, it's credible enough to try if you live in OpenCode, but verify it works for your specific provider before relying on it for cost reporting.
