abtop
graykode
btop-style terminal dashboard for live monitoring of Claude Code, Codex and OpenCode agent sessions.
What is abtop?
A btop/htop-style terminal UI that monitors local AI coding-agent sessions in real time across Claude Code, Codex CLI and OpenCode. It shows token usage, context-window fill, rate-limit consumption, child processes and orphan ports, reading local profile directories with no API keys or auth.
Pros & Cons
Pros
- At-a-glance multi-session view of tokens, context %, rate limits and orphan ports, read-only and key-free
- True cross-platform (macOS, Linux, Windows), 99.7% Rust, multiple install paths
- Actively iterated (v0.4.8, 34 releases), MIT, by an established OSS author
Cons
- Early 0.x, feature surface still evolving
- Coupled to specific agent CLIs' on-disk formats, so it breaks if those change
- Reads local files rather than official APIs, so metrics are best-effort (OpenCode needs sqlite3)

When it is interesting
Juggling several Claude Code or Codex sessions and wanting a live dashboard of tokens, context and rate limits.
When it is too early
If you run a single agent session, or need to monitor agents outside the supported CLIs.

RTK
rtk-ai
CLI proxy that compresses shell command output before your AI coding assistant sees it, cutting tokens 60-90%.
TOON
toon-format
Token-Oriented Object Notation - a compact serialization format that uses ~40% fewer tokens than JSON.
