Browse.dev alternative
Local browser automation for coding agents
DevSnoop is a Browse.dev alternative for developers who want browser automation through their own Chrome. Coding agents get page summaries, selectors, screenshots, console logs, network failures, and UI actions through a local HTTP API.
Choose DevSnoop when your agent work happens on your development machine and you want one local Chrome extension instead of a hosted browser session.
Browse.dev support notes
Browse.dev-style hosted browsers are useful when you need remote, disposable sessions. DevSnoop fits a different loop: the page is already open in your Chrome, the local app is already running, and the agent needs inspect-click-debug feedback without moving the session somewhere else.
Local state stays usable
The agent can work against the same cookies, tunnel domains, extension state, and hot-reloaded frontend tab that you are using during development.
Small checks stay small
A page summary, selector lookup, click, diff, or console-log check can run as one local HTTP command instead of starting a hosted browser session.
Cost stays predictable
DevSnoop is priced as a local tool. Repeated agent checks during implementation do not create metered browser-session usage.
The usual browser-agent path
- Hosted browser workflows add another account, another remote runtime, and usually another usage meter.
- Agents often need repeated screenshots or raw browser protocol context before they can make a small frontend decision.
- Pricing can scale with requests, sessions, or seats even when the work happens on your own development machine.
What DevSnoop changes
- Runs through local Chrome with a Native Messaging host on your machine.
- Returns compact JSON for page summaries, selectors, DOM diffs, console logs, network failures, and screenshots.
- Costs $29 once, with no request metering, usage limit, or seat limit.
Best fit
- Frontend implementation checks in local or staged apps.
- Coding agents that need to click, fill, inspect, and debug Chrome tabs.
- Developers who want a browser automation tool with local data flow and one-time pricing.
Use DevSnoop when your coding agent needs to inspect and operate the browser you already use for development.
