NanoClaw vs browser-use: Which Should You Use?

Hey there! Laura and Heidi here from SCRNIFY!

NanoClaw and browser-use both help agents do useful work, but they are not the same kind of tool.

We like comparisons like this because the wrong answer is usually expensive. If you ask a browser tool to become your whole assistant system, it gets weird. If you ask an assistant harness to be your deterministic browser runner, also weird.

browser-use is a browser automation agent framework. It gives AI agents a way to open pages, inspect state, click elements, fill forms, run browser tasks, and return results. It has open-source packages, SDKs, CLI workflows, and cloud browser infrastructure.

NanoClaw is a personal agent harness. It connects messaging channels, scheduled jobs, memory, skills, credentials, and containerized agent sessions. Its job is broader: "let me message an assistant and have it run work safely over time."

So the useful comparison is not "which one is better?" It is "where should the agent live, and how much of the job is browser work?" Much less dramatic. Much more useful.

Last checked: 2026-06-02. NanoClaw and browser-use are moving quickly, so verify current install steps, supported channels, SDK behavior, and cloud features before building on either.

At a glance

Question	NanoClaw	browser-use
Main layer	Personal assistant harness	Browser automation agent
Entry point	Chat channel, schedule, or agent group	Python, TypeScript, CLI, SDK, or cloud task
Best for	Long-running delegated work	Browser navigation and extraction
Isolation focus	Per-agent containers and explicit mounts	Browser/session infrastructure
Output shape	Message, scheduled report, memory update, task result	Browser task result, extracted data, screenshots, recordings
Use together?	Receives and routes the request	Executes browser-specific portion

Short answer

Use browser-use when the core job is browser automation.

Use NanoClaw when the core job is delegation from a person: chat messages, scheduled tasks, memory, credentials, containers, and recurring agent work.

For many workflows, the clean split looks like this:

NanoClaw receives the human request
NanoClaw keeps the agent session, schedule, and channel context
browser-use handles browser-specific tasks inside that workflow
Screenshots, logs, URLs, and notes become evidence
Confirmed behavior can later become a deterministic Playwright or Puppeteer check

That is the main point. NanoClaw is closer to the assistant layer. browser-use is closer to the browser action layer. Mixing those up is how a small automation job turns into a weekend infrastructure hobby.

What browser-use is good at

browser-use is built for AI agents that need to operate a browser.

That includes:

Filling forms from instructions
Extracting data from pages that are hard to scrape directly
Researching products, jobs, tickets, or support pages
Navigating sites where selectors are not known ahead of time
Running one-off browser tasks from Python, TypeScript, CLI, or cloud SDKs
Using managed browser infrastructure when local Chrome is the wrong layer

A typical browser-use task starts with a browser goal. The current open-source quickstart looks like this:

import asyncio
from browser_use import Agent, Browser, ChatBrowserUse

async def main():
    browser = Browser()
    agent = Agent(
        task='Find the number of stars of the browser-use repo',
        llm=ChatBrowserUse(),
        browser=browser,
    )
    await agent.run()

asyncio.run(main())

The value is that the agent can adapt while moving through the page. You do not need to know every selector before the run starts.

That flexibility is useful when the browser is the hard part.

What NanoClaw is good at

NanoClaw is built for personal agent operations.

The browser may be part of the job, but it is not the whole job. NanoClaw focuses on:

Messaging channels like Telegram, WhatsApp, Slack, Discord, email, and others
Per-agent containers and explicit filesystem mounts
Scheduled jobs that can message results back
Memory and per-agent workspaces
Skills that add only the channels or providers you want
Credential handling through an agent vault rather than raw keys inside the container
Custom forks where behavior changes through code, not config sprawl

A typical NanoClaw request sounds like something you would send to a teammate:

@Andy check the competitor pricing pages every Monday morning.
If anything changed, send me the old price, new price, URL, and screenshot.
Only inspect the public pricing pages. Do not log into accounts.

That request includes scheduling, channel delivery, memory, permissions, and browser work. browser-use can help with the browser part. NanoClaw owns the surrounding assistant workflow. The boring plumbing is the product here.

Where they overlap

The overlap is browser work inside long-running agent workflows.

NanoClaw can run agents in containers. Those agents can use tools. A browser-use script or SDK call can be one of those tools if you wire it in.

For example:

You message NanoClaw from Telegram: "Check the staging checkout flow."
NanoClaw routes the request to the right agent group.
The agent runs a browser-use task against the staging URL.
browser-use navigates the flow and gathers observations.
The agent attaches screenshots or links to the report.
NanoClaw sends the result back through Telegram.

In that setup, browser-use does not replace NanoClaw. NanoClaw does not replace browser-use. They sit at different layers.

Use browser-use when the browser is the product surface

browser-use fits when the task is mostly about navigating a website.

Good fits:

"Find and summarize listings from this marketplace"
"Fill this application form using these details"
"Open this SaaS app and inspect what changed"
"Collect visible pricing from these pages"
"Use a remote browser with proxy and CAPTCHA support"

The strongest browser-use workflows have a narrow browser goal and a clear result format:

Visit these five pricing URLs.
For each page, return plan names, monthly prices, annual prices if visible, and screenshot filenames.
If a price is hidden behind login or sales contact, mark it unavailable.
Do not infer prices from old snippets or search results.

That prompt makes the browser task auditable. It also tells the agent when not to guess.

Use NanoClaw when the workflow starts in chat

NanoClaw fits when the task belongs to a person, schedule, or channel.

Good fits:

"Message me every morning with a short briefing"
"Watch this repo and tell the team when a release lands"
"Run an agent from WhatsApp while I am away"
"Give this agent access only to this folder"
"Keep one memory for this project and another for personal tasks"
"Run scheduled jobs in isolated containers"

The browser may still matter. It is just one tool among many.

A useful NanoClaw request includes boundaries:

@Andy review the public docs site after each Friday deploy.
Check homepage, pricing, docs, and blog pages.
Capture screenshots for visual issues.
Send a short report to Slack with what passed, what failed, and what was not verified.
Do not modify code.

That is recurring delegated work with a delivery channel and a safety boundary.

Decision table

Job	Better fit	Why
One-off browser research	browser-use	The task is mainly navigation and extraction
Scheduled personal assistant task	NanoClaw	Needs schedule, memory, and message delivery
Fill a web form from provided data	browser-use	Browser interaction is the core work
Run an agent from Telegram or WhatsApp	NanoClaw	Channel routing is the entry point
Keep separate agents for work and personal context	NanoClaw	Isolation and per-agent workspace matter
Use managed browsers with proxy or CAPTCHA support	browser-use	Browser infrastructure is the hard part
Send recurring status updates to a chat group	NanoClaw	Delivery and recurrence matter more than browsing
Inspect a page and return screenshots	browser-use first	The browser task is narrow and visual
Coordinate files, shell, web, memory, and chat	NanoClaw	Multi-tool assistant workflow
Turn a vague chat request into a browser run	Both	NanoClaw receives it, browser-use executes the browser portion

If the task begins with "open this site," start with browser-use.

If the task begins with "message me," "watch this," "run every week," or "keep this agent available," start with NanoClaw.

Main risks

browser-use risk is agent drift.

An agent may click the wrong thing, stop too early, miss hidden state, or summarize without enough proof. Managed browser infrastructure can help with scale, stealth, and production reliability, but it does not remove the need for clear task contracts.

For browser-use runs, ask for:

URLs visited
Steps taken
Screenshot filenames
Data fields returned
What was not accessible
What was inferred versus directly observed

NanoClaw risk is operational trust.

It is personal infrastructure. It can connect channels, folders, schedules, credentials, and agents that run over time. Container isolation helps, but you still need to decide what each agent can see and do.

For NanoClaw, ask:

Which channels can reach this agent?
Which folders are mounted?
Which credentials can be injected?
Which jobs can run on a schedule?
Where are logs and memory stored?
Who can trigger or pause a task?

Different risks. Different controls. Same rule we keep relearning: make the tool show its work.

When not to use either

Do not use browser-use or NanoClaw for every browser-adjacent job.

If the task is a known CI check with fixed selectors and a clear pass/fail result, use Playwright or Puppeteer. A browser agent adds cost and variation where a test runner should be boring.

If the task is one quick interactive browser run, NanoClaw is probably too much infrastructure. Use browser-use directly, or use a normal browser automation script.

If the task is a scheduled assistant workflow with chat delivery, memory, and permissions, browser-use alone is too narrow. It can run the browser portion, but it does not own the broader assistant system.

That boundary matters. Tools get flaky when they are asked to be a layer they were not built to be. They also become annoying to explain to teammates, which is usually the first warning sign.

How screenshots fit

Both tools need visual evidence when they make visual claims.

If browser-use says a form submitted, save the screenshot that shows the confirmation state. If NanoClaw sends a weekly report that a pricing page changed, attach the screenshot or Capture that proves it.

Good evidence includes:

URL
Viewport
Timestamp
Step name
Screenshot or video file
Notes about what was not verified

The screenshot does not replace the agent report. It keeps the report honest.

Where remote Capture fits

browser-use and NanoClaw can both operate browser workflows, but sometimes you only need a stable visual artifact by URL.

Remote Capture is useful for:

Public pricing pages
Docs pages
Deploy preview screenshots
Scheduled monitoring
Agent reports that need archived page images

With scrnify, the Capture is sent to the Scrnify API instead of requiring every assistant host or browser task to manage local Chrome:

scrnify capture https://example.com/pricing \
    --type image \
    --format png \
    --full-page

Use this when the URL alone is enough to recreate the page state. Do not use it for a logged-in cart, an agent's current browser tab, or a flow that depends on temporary session state unless you can recreate that state remotely.

That boundary is important. Remote Capture does not replace browser-use for interactive tasks. It does not replace NanoClaw for messaging, schedules, or memory. It gives either workflow a repeatable way to collect page evidence when the page can be reached by URL.

Recommended workflow

For production-ish agent workflows, the best setup is usually layered:

NanoClaw receives the request, owns the schedule, and sends the result back
browser-use handles browser tasks that need navigation or judgment
Remote Capture handles repeatable screenshots of reachable URLs
Playwright or Puppeteer handles confirmed checks that should fail CI
Humans review ambiguous findings before turning them into policy

This avoids turning NanoClaw into a browser automation framework. It also avoids turning browser-use into your whole personal assistant system.

Use each tool at the layer where it is boring.

Final rule

Ask one question before choosing:

Is the hard part the browser task, or the assistant workflow around it?

If the hard part is browsing, use browser-use.

If the hard part is chat, scheduling, memory, isolation, and long-running delegation, use NanoClaw.

If the job starts in chat and ends in a browser, use both.
