optimAIzr v0.13.0 adds VS Code extension for tracking AI coding-agent usage
The developer of the open-source tool optimAIzr says it shipped v0.13.0, adding a VS Code extension that shows live context usage, cache countdowns, five-hour limits and savings inside the editor. The tool tracks and helps optimize usage across Codex, Claude Code and OpenCode, and the developer describes it as free, fully local, requiring no account and uploading no prompts. The idea came from the developer's own analysis showing that rereading context accounted for 56% of their AI usage costs.
It gives AI developers a local, editor-native way to see context consumption and rate-limit windows across multiple coding agents, though the feature set, privacy guarantees and savings claims come only from the developer.
I’ve been building optimAIzr, an open-source AI usage optimizer. I’m a senior SWE and use Codex/Claude Code daily, both professionally and to build this project.
The idea came after analyzing my own usage and discovering that 56% of my AI usage costs came from rereading context.
It tracks and helps optimize usage across Codex, Claude Codeand OpenCode.
Just shipped v0.13.0, adding a VS Code extension with live context usage, cache countdowns, 5h limits and savings directly in the editor.
