Caveman
Open-source AI cost-optimization toolkit and cloud for coding agents: routing, caching, compression and cost detection.
Four free tools for coding agents: Caveman cost optimization, Petdex's 4,800+ desktop pets, Codex Resets usage tracking, and CodexGuide tutorials.
4 Developer Tools tools are tracked in this index. 4 of them ship a free plan (Caveman, Petdex, Codex Resets, CodexGuide). Most common tags on this page: AI (4 tools), Research (4 tools), Web (4 tools). Pricing figures behind these entries were last checked between 2026-09-28; every tool page carries its own check date.

When you compare Developer Tools tools, the fields that decide the outcome are the ones this index actually stores: whether a free plan exists and what it limits, the published entry price and how it bills (per seat, per month, per workspace), what the trial covers, which of the six index dimensions the tool scores on, when each figure was last checked against the official page, and which alternatives sit in the same category. Each tool page prints those fields with its own verification date, the Developer Tools comparison pages put two products side by side on the same fields, and the list pages rank the category against the rest of the index — so you can move from a shortlist to a decision without opening a vendor's sales page.
