CodeBurn is a terminal TUI dashboard that reads AI coding session data directly from disk — no API keys, proxies, or wrappers required — and surfaces a breakdown of token costs across Claude Code, Codex, Cursor, GitHub Copilot, and more. It auto-classifies activity into 13 categories (coding, debugging, testing, refactoring, etc.) and shows one-shot success rates per task type, giving developers a rare look at where their AI spend actually goes. The dashboard includes gradient charts, keyboard navigation, multiple time periods, and a currency converter supporting 162 ISO 4217 currencies. There's also an "optimize" command that scans sessions for waste patterns and outputs actionable, copy-paste fixes. For teams, a macOS menu bar app surfaces daily costs at a glance. With 2.7k stars after a Show HN post, CodeBurn clearly scratched a real itch. As AI coding budgets scale from hundreds to thousands of dollars per developer per month, tooling that makes costs visible and actionable becomes less optional and more essential.

Pi-Mono is an MIT-licensed monorepo by developer Mario Zechner (the creator of libGDX) containing a suite of packages for building LLM-powered agents: a unified multi-provider API (OpenAI, Anthropic, Google), an interactive coding agent CLI, an agent runtime with tool calling, TUI and web UI libraries, a Slack bot integration, and CLI tooling for deploying vLLM pods on GPU infrastructure. The design philosophy is deliberate minimalism — each package is self-contained, composable, and avoids abstractions that obscure what the LLM is actually doing. The pi-coding-agent is the flagship: it takes a task, breaks it into steps, runs shell commands and edits files, streams its reasoning to a rich terminal UI, and confirms destructive actions before executing. It's closer in spirit to a hands-on CLI coding partner than a one-shot code generator. With 32,800 GitHub stars, Pi-Mono has real traction in the developer community — particularly among engineers who are tired of opaque agent frameworks and want to own their toolchain. The "share your sessions publicly to improve training data" encouragement is an interesting contribution loop that distinguishes it from purely proprietary tools.
Reviewer scorecard
“This is exactly the observability layer AI coding has been missing. Knowing that 40% of my Claude Code tokens went to a single poorly-scoped context window is the kind of insight that pays for itself in the first week. The 'optimize' command is genuinely useful, not just marketing copy.”
“The unified LLM provider API alone is worth bookmarking — switching between Claude, GPT-4o, and Gemini without rewriting your agent logic is genuinely useful. The coding agent's step-by-step terminal UI is also much easier to debug than black-box agent frameworks.”
“The multi-provider claim is impressive on paper, but Cursor and Copilot don't expose session data the same way Claude Code does. Expect incomplete data for non-Anthropic tools until the provider ecosystem standardizes telemetry formats. Also: if your team uses ephemeral dev containers, good luck getting disk reads to work.”
“The monorepo structure means you're taking on a lot of footprint for each component you actually need. Mario is a talented developer but a one-person project at this scope carries real maintenance risk — don't build production workflows on an unstable package graph.”
“Cost observability is the missing infrastructure layer for the AI-native development era. Just as APM tools like Datadog became mandatory once cloud costs mattered, AI coding cost tracking will be table stakes within 18 months. CodeBurn is an early mover in a category that will consolidate around one or two dominant players.”
“The 'share sessions for training data' concept is quietly subversive — it turns every Pi-Mono user into an inadvertent AI trainer. Open-source agent toolkits that build community feedback loops into their design are going to compound faster than closed systems.”
“The TUI design is clean and keyboard-navigable in a way most developer dashboards aren't. Gradient charts inside a terminal window sounds tacky but actually reads well. The category breakdown would make a genuinely compelling weekly standup artifact for teams trying to improve AI workflow discipline.”
“This is firmly a developer tool — the TUI and web components are functional but not approachable for non-technical users. Unless you're comfortable reading TypeScript and configuring LLM API keys, the setup cost isn't worth it for content workflows.”
