Caveman Cloud alternatives for solo developers
TL;DR: to see spend, start with your provider's usage console and add Langfuse (free to self-host) if you need per-feature detail. To cut spend, compress what your agents read with SuperCompress or Headroom, and filter shell output with RTK.
Caveman Cloud is aimed at companies running many agents: cost per task across agents, evals, monitors, suggested fixes, model routing, a semantic cache and governance. Per its pricing page it has a free plan for one person and a Team plan at $300 a month that includes $300 of usage. If you build alone, you may not need a console at all. Here is the lighter stack.
1. See your spend
Your provider's usage console
Anthropic, OpenAI and Google all show cost by key, model and day. Create one API key per project and the console becomes a per-project dashboard for free. In Claude Code, /cost shows what the current session has spent.
Langfuse
When you need cost by feature or by user inside your own app, Langfuse traces every LLM call with token and cost tracking. The core is MIT-licensed and free to self-host, with a hosted free tier as well.
2. Cut your spend
SuperCompress
Most of an agent's tokens are input: logs, file reads, tool results. SuperCompress is hosted, question-aware compression that keeps the original lines that answer the current question and drops the rest. One command wires it into the coding agents on your machine, with a free tier of 5M tokens a month.
Headroom
The open-source, run-it-yourself route to the same goal, with content-type compressors and the originals kept retrievable. Apache 2.0.
RTK
A small open-source filter for noisy shell commands. Quick to install alongside either of the above.
The solo stack, side by side
| Need | Tool | Cost to start |
|---|---|---|
| Spend by project | Provider console, one key per project | Free |
| Spend by feature or user | Langfuse | Free self-hosted |
| Fewer input tokens | SuperCompress or Headroom | Free tier / free |
| Smaller shell output | RTK | Free |
When Caveman Cloud is worth it
Once several people run agents and you need caps, evals and governance across all of them, a team console starts to pay for itself, and Caveman Cloud's free single-user plan is an easy way to try it. Until then, the stack above covers seeing and cutting spend for very little money. More options: best Caveman Cloud alternatives.

Disclosure: Loopy and SuperCompress are both built by Arjun Shah, so this post is not neutral. Other tools are described from their own docs and public reporting, with links. Check each one for current details.
