Such as when you want to inject a large js helper to the page, chromedp will crash.

crash_chromedp.go

package main

import (
	"context"
	"fmt"
	"log"
	"strings"

	"github.com/chromedp/chromedp"
)

func main() {
	ctx, cancel := chromedp.NewContext(context.Background())
	defer cancel()

	var res string
	err := chromedp.Run(ctx,
		chromedp.Navigate(`https://example.com/`),
		chromedp.Evaluate(fmt.Sprintf(`"%s"`, strings.Repeat("t", 2_000_000)), &res),
	)
	if err != nil {
		log.Fatal(err) // will fail at here: context canceled
	}

	log.Println(len(res))
}

Rod doesn't have this limitation:

package main

import (
	"fmt"
	"log"
	"strings"

	"github.com/go-rod/rod"
)

func main() {
	page := rod.New().MustConnect().MustPage("https://example.com/")
	res := page.MustEval(fmt.Sprintf(`"%s"`, strings.Repeat("t", 2_000_000))).Str()
	log.Println(len(res)) // Output: 2000000
}
