Ripper gratuiti del sito descritti da Semalt Expert

Feb 08, 2018

Darcy Ripper è uno dei migliori strumenti gratuiti per la creazione di siti su Internet. Ti permette di strappare o scaricare il sito intero o parziale all'istante. È quindi possibile salvare i documenti Web sul disco rigido per la navigazione offline. Darcy Ripper ha tre strutture di ripping del sito essenziali: gerarchie, web e sequenze e lo strumento viene utilizzato per raschiare i dati da un sito. Darcy Ripper è la scelta prioritaria per i webmaster e strappa tutti i tipi di siti in pochissimo tempo. È possibile utilizzare questo programma su base regolare e svolgere più attività di ripping del sito alla volta. Esistono due tipi di modalità di apprendimento: Modalità avanzata e Modalità guidata. L'interfaccia utente point-and-click di Darcy Ripper ti consente di estrarre tutto il testo da un sito gratuitamente, e puoi scaricare l'intero contenuto web e archiviarlo in formato TXT, Excel o HTML.

Caratteristiche generali di Darcy Ripper:

Essendo un sito di ripper gratuito, Darcy Ripper è configurabile e puoi controllare cosa succede ai tuoi dati scaricati o estratti. È inoltre possibile specificare più host su cui eseguire il lavoro. Darcy Ripper ha un'interfaccia grafica interattiva e ti permette di rielaborare i dati in tempo reale. Inoltre, supporta sia i file HTTP che HTTPS e viene fornito con un server proxy per facilitare il tuo lavoro. Il numero di connessioni per server e la limitazione della larghezza di banda dipendono dal codice di risposta HTTP.

Oltre a Darcy Ripper, HTTrack e Cyotek WebCopy sono due strumenti di ripper sito interattivi e gratuiti.

1. HTTrack:

Essendo un servizio di ripper sito gratuito, HTTrack è noto per la sua interfaccia user-friendly e semplifica il download o lo strappo dell'intero sito web. Puoi iniziare con la sua modalità guidata e puoi strappare tutte le pagine web che vuoi. Con HTTrack puoi facilmente copiare testo, immagini e file multimediali senza compromettere la qualità. Viene principalmente utilizzato per indirizzare directory, pagine gialle, forum di discussione e pagine Web dinamiche.

2. Cyotek WebCopy:

Proprio come HTTrack, Cyotek WebCopy è un servizio di ripper sito gratuito che consente di estrarre il sito Web parziale o completo. È possibile scaricare diversi documenti Web sul disco rigido per la lettura offline. Questo strumento esegue principalmente la scansione delle pagine Web specificate prima di estrarne il contenuto e utilizza una rimappatura automatica per indirizzare sia Internet che i collegamenti esterni. Puoi personalizzare questo servizio in base alle tue esigenze e puoi escludere alcune parti di un sito che non sono vantaggiose per la tua attività.

Conclusione:

Senza dubbio, Darcy Ripper è potente come HTTrack e Cyotek WebCopy. È un servizio di ripper di sito relativamente nuovo ma possiede varie caratteristiche. In effetti, tutti questi strumenti gratuiti di ripper del sito hanno i loro pro e contro, ed è difficile nominare l'opzione migliore. Tuttavia, HTTrack è in giro da un po 'di tempo ed è la scelta prioritaria per sviluppatori web, programmatori e webmaster. D'altra parte, Darcy Ripper impiegherà sicuramente del tempo per conquistare il cuore di tutti gli uomini d'affari.
