Nitter is a free and open-source alternative Twitter front-end.
Nitter’s advantages are:
- No JavaScript or ads
- All requests go through the backend — the client never talks to Twitter
- Prevents Twitter from tracking your IP or JavaScript fingerprint
- Lightweight (profiles pages tend to be 60 KB instead of 600 KB)
- RSS feeds
There are also many other instances of Nitter. It is about 15 times lighter than Twitter.
Nitter has several browser extensions maintained by the community.
