Always the same name
Every request carries the User-Agent above: no rotation, no disguise, no borrowed browser name.
For site owners
NagareBotreads in the open.
The crawler behind Nagare. It says who it is, follows your robots.txt and never tries to get around you.
Nagare keeps a dated record of public web pages for product teams: what changed, when, and what it means. NagareBot is the robot that reads those pages.
Its User-Agent
NagareBot/0.1 (+https://nagare.watch/bot)
The version number changes. The name NagareBot does not.
Why it visits your site
Someone using Nagare follows your company. NagareBot reads the public pages of your site that matter to them — pricing, product, docs, changelog, careers — on a schedule: once a day or once a week, sometimes on request.
It reads what anyone can see without an account, and nothing else. Nagare does not disclose which customers follow a site.
How it behaves
Your robots.txt decides
NagareBot follows the rules you write for it, or those for every robot (*) when there are none. It reads your robots.txt again at least once an hour. If your robots.txt answers with a server error, it reads nothing.
A polite pace
When it reads your server directly: one request at a time, at least a second apart, longer if your Crawl-delay asks for it. A 429 or a server error makes it pause; it tries again a few times at most, then moves on.
Your site, nothing else
It follows links within your site only. Links to other sites are noted, never followed.
Public pages only
It never logs in, never fills in a form and never tries to get past a paywall.
No workarounds
No disguise, no anti-bot bypass, no CAPTCHA solving. If you block NagareBot, it stays blocked.
Two ways of reading
NagareBot reads a site either directly, from Nagare’s servers, or through Firecrawl, a service that renders pages the way a browser does, for sites that need JavaScript. Firecrawl’s requests carry the NagareBot User-Agent too and come from Firecrawl’s servers; Firecrawl applies robots.txt for its own robot as it reads. Nagare then checks every page against your rules for NagareBot, and keeps nothing NagareBot is not allowed to read.
Limit or block it
Everything goes through your robots.txt. A change applies within the hour.
Keep it out
User-agent: NagareBot
Disallow: /Close one section
User-agent: NagareBot
Disallow: /private/Slow it down
User-agent: NagareBot
Crawl-delay: 10Seconds between two requests, when it reads your server directly.
Blocking it in robots.txt is enough.
