This repository contains a list of of HTTP user-agents used by robots, crawlers, and spiders as in single JSON file.
- NPM package: https://www.npmjs.com/package/crawler-user-agents
- Go package: https://pkg.go.dev/github.com/monperrus/crawler-user-agents
- PyPi package: https://pypi.org/project/crawler-user-agents/
Each pattern is a regular expression. It should work out-of-the-box wih your favorite regex library:
Download the crawler-user-agents.json file from this repository directly.
crawler-user-agents is deployed on npmjs.com: https://www.npmjs.com/package/crawler-user-agents
To use it using npm or yarn:
npm install --save crawler-user-agents
# OR
yarn add crawler-user-agentsIn Node.js, you can require the package to get an array of crawler user agents.
const crawlers = require('crawler-user-agents');
console.log(crawlers);Install with pip install crawler-user-agents
Then:
import crawleruseragents
if crawleruseragents.is_crawler("googlebot/"):
# do somethingGo: use this package,
it provides global variable Crawlers (it is synchronized with crawler-user-agents.json),
functions IsCrawler and MatchingCrawlers.
Example of Go program:
package main
import (
"fmt"
"github.com/monperrus/crawler-user-agents"
)
func main() {
userAgent := "Mozilla/5.0 (compatible; Discordbot/2.0; +https://discordapp.com)"
isCrawler := agents.IsCrawler(userAgent)
fmt.Println("isCrawler:", isCrawler)
indices := agents.MatchingCrawlers(userAgent)
fmt.Println("crawlers' indices:", indices)
fmt.Println("crawler' URL:", agents.Crawlers[indices[0]].URL)
}Output:
isCrawler: true
crawlers' indices: [237]
crawler' URL: https://discordapp.com
I do welcome additions contributed as pull requests.
The pull requests should:
- contain a single addition
- specify a discriminant relevant syntactic fragment (for example "totobot" and not "Mozilla/5 totobot v20131212.alpha1")
- contain the pattern (generic regular expression), the discovery date (year/month/day) and the official url of the robot
- result in a valid JSON file (don't forget the comma between items)
Example:
{
"pattern": "rogerbot",
"addition_date": "2014/02/28",
"url": "http://moz.com/help/pro/what-is-rogerbot-",
"instances" : ["rogerbot/2.3 example UA"]
}
