Claudectl is a free, open-source terminal supervisor for running multiple Claude Code sessions from a single unified dashboard. Instead of hunting between tabs to check on parallel agent runs, you get real-time visibility into status, spend rate, context window usage, CPU, and memory for every active session simultaneously. The operational features are where it earns its keep: set per-session budget caps that automatically kill runaway agents before they drain your API credits, approve pending prompts from the dashboard without switching contexts, and run dependency-ordered workflows where task completion triggers the next step. Desktop notifications, shell hooks, and webhooks fire when a session needs attention. For teams scaling autonomous coding work, claudectl also records sessions as GIFs or terminal casts — useful for documentation, debugging, or showing clients what the agent actually did. It installs via Homebrew or Cargo, supports macOS and Linux across eight terminal emulators, and ships with a demo mode for risk-free evaluation. A genuinely useful piece of infrastructure that fills a gap Anthropic hasn't addressed natively yet.

Dirac is an open-source AI coding agent built by Dirac Delta Labs that shot to the top of TerminalBench-2 with a 65.2% score using Gemini Flash — while costing 64.8% less than competing agents. Forked from Cline and rebuilt with a performance-first architecture, it handles file modifications, multi-file refactoring, terminal commands, and browser automation through an approval-based workflow. What sets Dirac apart is its technical substrate: hash-anchored edits replace fragile line-number targeting with stable content hashes, AST-native processing understands language structure for TypeScript, Python, and C++, and multi-file batching reduces LLM roundtrips by processing several files per call. The result is a leaner context that preserves model reasoning quality without burning through tokens. Available as both a VS Code extension and an npm CLI, Dirac supports Anthropic, OpenAI, Google, Groq, and Mistral as backends. Its Apache 2.0 license and strong TerminalBench showing on the affordable Gemini Flash model make it a compelling pick for developers who want production-grade coding assistance without the per-token bill shock.
Reviewer scorecard
“Running 4+ parallel Claude Code sessions without a unified view is chaos. Claudectl gives me a single pane showing spend rate, context window usage, CPU, and activity for all of them simultaneously. The budget kill-switch alone has saved me from runaway agent spend multiple times. Free, open-source, Homebrew installable — this is essential infrastructure for anyone serious about multi-agent coding.”
“Topping TerminalBench-2 while being 64.8% cheaper is the kind of benchmark that actually matters to developers. The hash-anchored editing and AST-native approach fix the two most annoying failure modes of existing coding agents — wrong line edits and syntax-blind refactors.”
“Claudectl solves a problem that only exists because Claude Code doesn't have a built-in multi-session dashboard yet. Anthropic will likely ship this natively, at which point claudectl becomes redundant. The terminal TUI is also limiting — no web UI, no mobile alerts, no team visibility. Useful today as a workaround, but not something to build workflows around long-term.”
“It's a Cline fork with smart optimizations — not a ground-up rethink. TerminalBench-2 scores are reproducible only if you're running similar tasks; complex real-world codebases may tell a different story. Also, requiring your own API key still means real money.”
“The ability to run dependency-ordered agent workflows — task A spawns tasks B and C, claudectl handles the sequencing — points toward agent orchestration becoming a developer discipline in its own right. The budget controls and cost visibility are early signals of what 'responsible AI spending' looks like at the individual developer level. Tools like this build the intuition the field needs.”
“The race to build the cheapest, most accurate coding agent is the real infrastructure play of 2026. Dirac's multi-provider support and lean context model are exactly the primitives that make agentic coding deployable at scale — not just on powerful machines.”
“Even for non-developers running content pipelines with a few Claude Code sessions, the spend monitoring alone is worth it. Knowing exactly what each session costs in real time changes how you structure prompts. The GIF/terminal cast recording for documentation is a nice bonus — I can show clients exactly how the agent built something.”
“The VS Code extension makes it approachable for designers who code. Approval-based workflows mean it won't silently rewrite your carefully named CSS classes. Worth trying if you've been burned by agents that act first and apologize later.”
