I built a free extension to track Claude's usage limits before you hit them

If you use Claude daily, you've probably hit a wall mid-task. The reason it's so easy: Claude doesn't have one limit. It has several. A rolling 5-hour session window A weekly pool shared by all models Separate weekly caps per model (Opus, Sonnet, Claude Design) And the weekly pool is sneaky: Fable has no cap of its own and draws that shared pool down ~2× faster than Opus . So you can burn the week without realizing it. I wanted that state visible at a glance instead of digging through settings, so I built Claude Usage Monitor — a small browser extension for Chrome and Firefox. What it does It puts a color-coded % badge in your toolbar , and one click shows the full breakdown: Current 5-hour session + live countdown to reset Weekly all-models pool (with the Fable draw-down flagged on the card) Per-model weekly caps: Opus, Sonnet, Claude Design Daily Claude Code routine runs Extra-usage credits + prepaid balance for pay-as-you-go Auto-detects your plan (Pro / Max 5x / Max 20x / Team), so every number matches your subscription Six themes The privacy part (the part I cared about most) It's open source (MIT) and runs 100% locally — no backend, no analytics, no servers. A design decision I'm happy with: the host permissions are scoped to exactly four claude.ai endpoints (org list, usage stats, routine-run budget, prepaid balance). It physically can't read your chats, projects or files. Narrow permissions = less to trust, and less to exploit. One honest caveat: it reads claude.ai's own usage endpoints, so it can break if Anthropic changes them. Not affiliated with Anthropic. Try it It's free, no account needed (desktop Chrome & Firefox): 🔗 claude-monitor.com Chrome Web Store Firefox Add-ons Happy to hear what else you'd want tracked — drop a comment.

Building a Bitcoin Education Platform, Contributing to Open Source, and Surviving a Hackathon

A few months ago, I didn't expect that I'd be spending my days debugging authentication flows, opening pull requests, analyzing backend architectures, and building a Bitcoin education platform during a hackathon. Yet here we are. What started as curiosity about Bitcoin turned into one of the most intense learning experiences I've had as a builder, and honestly, I wouldn't trade it for anything. This is the story of how I joined Hack4Freedom Lagos 2026, helped build BitPath, contributed to open source, discovered OpenCode, and learned that software engineering is often just solving one problem after another until things somehow start working. How I Ended Up Building in Bitcoin My interest in Bitcoin didn't start from price charts or trading. What attracted me was the builder ecosystem around it. I've contributed to open source before, so I already appreciated the value of collaborative software development. But what stood out about Bitcoin was how deeply open source is woven into the culture. In many ecosystems, open source feels like an option. In Bitcoin, it feels like a foundation. Everywhere I looked, people were building in public, contributing to projects, improving documentation, reviewing code, and helping newcomers find their footing. That environment made me want to participate more deeply. When the opportunity came to join the Hack4Freedom Lagos 2026 hackathon, I said yes. The Project: BitPath Our team worked on BitPath, an AI-powered learn-and-earn platform designed to make Bitcoin education more accessible. The idea was simple: Instead of overwhelming learners with technical concepts, BitPath uses conversational learning experiences, AI tutoring, quizzes, progress tracking, and rewards to help users learn Bitcoin and financial literacy in a more engaging way. Our stack looked something like this: Frontend Next.js TypeScript Tailwind CSS Zustand Backend NestJS PostgreSQL Redis Queue processing Additional Services Google OAuth OpenAI APIs Lightning Network

Week 2: Pull Requests, Rejected Code, and the Art of Not Breaking Things

GSoC 2026 | CircuitVerse × Canvas LMS LTI 1.3 Integration If Week 1 was about getting familiar with the codebase and understanding what needed to be built, Week 2 was about learning the hard way that writing code is only half the job. The other half — the messier, more humbling half — is getting that code accepted by the people who actually maintain the project. This week was full of detours, rejected pull requests, reviewer feedback that stung a little, and a surprisingly frustrating fight with a two-letter word in Ruby. But by the end of it, I had something real to show: a clean, reviewed, and submitted change to CircuitVerse that lays the foundation for the entire LTI 1.3 integration. Let me walk you through it. A Quick Refresher: What Are We Building? CircuitVerse is an open-source platform where students can build and simulate digital circuits right in their browser. The project I'm working on aims to connect CircuitVerse with Canvas, one of the most widely used Learning Management Systems (LMS) in universities around the world. The technology that makes this connection possible is called LTI — Learning Tools Interoperability. Think of it as a universal plug that lets any educational tool (like CircuitVerse) slot into any LMS (like Canvas) so that students can log in once, get assignments, submit work, and have their grades flow back automatically — all without leaving their course page. There are two versions of this plug: LTI 1.1 , which is old and uses a simpler (but outdated) security mechanism, and LTI 1.3 , which is newer, more secure, and what Canvas actually recommends today. My job is to bring CircuitVerse fully up to LTI 1.3 standards. Monday–Tuesday: A Pull Request That Taught Me to Read Diffs I started the week with what I thought was a solid pull request (PR) — a fix for a bug in CircuitVerse's existing LTI 1.1 grade passback feature. "Grade passback" is the process where CircuitVerse sends a student's score back to Canvas after they complete an as
