stagewise is an open-source AI coding agent built specifically for frontend work on existing codebases. Unlike agents that only read source files, stagewise runs in its own browser environment — it can see the live DOM, observe console errors, and interact with the actual rendered UI before making code edits. This closes the loop between "here's the code" and "here's what the user actually sees." It's BYOK (bring your own key) with support for any major LLM, and is explicitly designed for established projects rather than greenfield apps — the agent understands how to navigate a real codebase and propose minimal, surgical edits. Launched April 16, 2026 and hit #6 on Product Hunt with 181 votes. The core insight is that frontend bugs are often invisible to agents working from source alone: a CSS cascade issue, a hydration mismatch, a console error — none of these appear in static file reads. stagewise makes these visible. For teams maintaining large frontend codebases, this is the agent setup that actually matches how human developers debug: look at the thing, then fix the code.

Tokemon
macOS overlay that monitors token usage across Claude, OpenRouter, ChatGPT in real-time

Tokemon is a lightweight macOS application that solves a surprisingly annoying problem: tracking token consumption across multiple AI services without refreshing half a dozen dashboards. It runs as a native menu bar app and displays a floating always-on-top overlay showing real-time usage metrics from Claude, OpenRouter, Amp, and ChatGPT — all in one place, updating every 60 seconds. The technical approach is straightforward but effective. Tokemon polls each service's usage API endpoint using credentials stored locally in `~/.config/tokemon/config.json`. Claude requires an org ID and session cookie, OpenRouter uses an API key, and others use bearer tokens. No data leaves your machine beyond the direct API calls — there's no external server, no telemetry, no account required. The design is intentionally extensible: adding a new service means adding a new entry in the config file. With the Claude Code Pro Max quota controversy making waves on Hacker News — users burning through $200/month plans in 90 minutes due to cache miss behavior — Tokemon's timing couldn't be better. For any developer juggling multiple AI subscriptions, having an always-visible token counter changes how you work: you start thinking about token budgets in real-time rather than discovering overages after the fact. The Apache 2.0 license and local-only architecture make this a trustworthy install. Small tool, real problem.
Reviewer scorecard
“Finally, an agent that doesn't need me to paste error messages manually. The browser-native visibility means it catches the runtime issues that trip up every other coding agent. BYOK is the right call — no lock-in, no data exposure concerns. I'd use this today on a legacy React codebase.”
“This is exactly the kind of zero-friction utility that should exist. Token anxiety is real for anyone running Claude Code on a Pro Max plan — a floating overlay that shows you're at 40% quota vs. discovering you're rate-limited mid-session is genuinely valuable. The extensible config system means you can add any service that exposes usage endpoints.”
“The browser-native approach adds real complexity: auth states, dynamic data, environment-specific behavior all make the 'live DOM' less deterministic than it sounds. I've seen agents make confident edits based on a logged-out state or a loading skeleton. The 'existing codebases' pitch needs battle-testing on something messier than a demo project.”
“Setting this up requires extracting session cookies from your browser for Claude — a process that's fiddly, breaks when sessions rotate, and creates a maintenance burden. macOS only means Windows and Linux users are out. And monitoring tokens doesn't fix the underlying problem; it just gives you better visibility into a bad situation.”
“The visual feedback loop is the missing link in agentic coding. As UI complexity grows, agents that can only read source files will hit a ceiling — stagewise points toward a future where agents debug by observation, not inference. This is how frontend maintenance gets automated.”
“Token budgets are the new RAM monitoring — developers who grew up tracking memory usage know instinctively how to optimize, and those who didn't get burned. Tokemon is the htop of the AI era. The broader pattern of OS-level AI resource monitoring will become standard tooling within two years.”
“As someone who spends half their time tweaking UI details, the idea of an agent that can actually see what I see is massive. Describing layout bugs in text is painful — stagewise removes that entire friction layer. Even if it only gets the fix right 60% of the time, that's a huge speed-up.”
“Even for non-developers using Claude for creative work, knowing when you're approaching your limit is essential. The floating overlay means you don't have to break your creative flow to check dashboards. Simple, focused, does one thing well — the kind of indie utility macOS has always done best.”
