CodeBurn is an open-source terminal dashboard that tracks and analyzes your token spend across Claude Code, OpenAI Codex, Cursor, OpenCode, and GitHub Copilot. It classifies coding sessions into 13 activity types — architecture, debugging, refactoring, code review, and more — and shows you exactly where your tokens are going. The standout feature is the optimizer: CodeBurn identifies wasteful patterns in your workflow — like repeatedly re-reading the same files, bloated context files, or MCP servers that are loaded but never used — and suggests concrete changes with estimated savings. It also tracks one-shot success rates per task type, helping you understand where AI is genuinely saving time vs. where you're fighting the tool. A macOS menu bar widget shows live token spend as you work, with a daily budget alert. Built by indie developer AgentSeal and shared as a Show HN, it picked up 80 upvotes and significant interest from developers who didn't realize how much they were spending on context re-reads alone. Open source under MIT license.

Evolver is an open-source agent evolution engine built on GEP — Genome Evolution Protocol — a novel framework that lets AI agents improve themselves autonomously over time. Rather than requiring manual prompt engineering or model fine-tuning, Evolver scans an agent's runtime logs and error traces, identifies failure patterns, and selects evolution assets called "Genes" (core behavioral units) and "Capsules" (composable skill modules) to address them. The system then emits structured prompts that drive systematic agent improvement — essentially writing better instructions for itself based on what went wrong. It integrates natively with Cursor, Claude Code, and OpenClaw via hook-based connectors. The architecture is offline-first with an optional EvoMap Hub for community-shared gene libraries. The project launched to 527 GitHub stars in a single day — an unusually strong reception that reflects how acutely developers feel the pain of agent reliability. If the self-improvement loop holds up in production, Evolver could shift agentic debugging from a manual slog to a continuous background process.
Reviewer scorecard
“I ran this on a week of Claude Code sessions and immediately found I was spending 30% of my tokens re-reading the same five config files. The menu bar widget is the killer feature — seeing the cost counter tick up while you work changes your behavior instantly. Instant install for anyone serious about AI coding.”
“This scratches a real itch — agent reliability is the #1 pain point right now and most solutions are 'add more evals.' Evolver's GEP loop is opinionated and that's a feature, not a bug. The Claude Code + Cursor hooks mean you can drop it into existing workflows today.”
“The 13 activity categories feel arbitrary and require calibration. More importantly, this is fundamentally a symptom-treating tool — the real fix is better context management built into the AI tools themselves. And if you're on a flat-rate API plan, cost tracking is largely irrelevant.”
“Self-evolving agents that modify their own prompts autonomously is a juicy concept, but the GPL-3.0 license and warning of a future 'source-available' shift is a red flag for production use. Also: if the agent evolves in a bad direction, do you notice before it ships to users?”
“Observability for AI token usage is an entire category about to explode. As agentic workflows scale from individual developers to teams and enterprises, understanding where tokens go becomes as important as understanding where CPU cycles go. CodeBurn is early but directionally correct.”
“GEP could become the RLHF of the agent era — a systematic mechanism for continuous improvement without human labeling. The Genome/Capsule abstraction is exactly the kind of modular primitive that scales well as agents get more complex and domain-specific.”
“Even for non-coding creative work — writing, research, brainstorming — understanding which prompting patterns are wasteful vs. effective is valuable. The one-shot success rate tracking by task type is a genuinely novel idea I haven't seen anywhere else.”
“For creative workflows where agents help with writing or design iteration, self-improving agents that learn from your rejection patterns could be genuinely magical. Imagine an agent that stops suggesting stock photography after you've rejected it 20 times — without you ever writing that rule.”
