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.

Langfuse is the open-source platform for observing, evaluating, and iterating on LLM applications in production. It captures every trace, span, and LLM call in your application, lets you run automated evaluations against ground truth datasets, and gives you a prompt management system with versioning and A/B testing built in. Native integrations cover OpenAI, Anthropic, LangChain, LlamaIndex, and any framework using OpenTelemetry. The self-hosted version is a single Docker Compose file, and the cloud version has a generous free tier. Recent releases have added support for multi-agent tracing, where you can visualize the full execution tree of a complex agent system with individual LLM call latencies, costs, and outputs at every step. With GitHub tracking showing renewed trending momentum this week (149 stars today), Langfuse is having a moment as developers building agentic systems discover they need real observability tooling. The alternative — logging to console and hoping for the best — doesn't scale past proof-of-concept. Langfuse is becoming the de facto standard for teams serious about production LLM systems.
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.”
“If you're running any LLM application in production without Langfuse, you're flying blind. The multi-agent tracing support that landed in recent releases is the killer feature — finally you can see exactly which agent call caused that 45-second latency spike or why a particular input keeps producing hallucinations. The self-hosted option is production-ready.”
“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.”
“Langfuse is good but the space is getting crowded fast — Braintrust, Phoenix (Arize), and now OpenTelemetry-native options from every cloud provider are all after the same market. The open-source moat isn't as deep as it looks when AWS or Azure bundles observability into their LLM services for free. Worth using, but don't over-invest in their specific abstractions.”
“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.”
“LLM observability is infrastructure, not a feature. As AI systems get more autonomous and make more consequential decisions, the ability to audit every decision in a complex agent chain becomes a regulatory and liability requirement, not just a developer convenience. Tools like Langfuse are building what will become mandatory compliance infrastructure.”
“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.”
“For creators building AI-powered content tools, the prompt management and versioning features are genuinely valuable — being able to A/B test prompt variants against real user inputs and see which version produces better creative outputs is a superpower. This is the kind of tooling that separates serious AI product builders from prompt-and-pray developers.”
