ToffeeShare Alternative: How BoltShare Compares
BoltShare Team · Last reviewed
ToffeeShare and BoltShare are close cousins. Both are free, both run in the browser with nothing to install, neither needs an account, and neither keeps your file on a server. If you already like ToffeeShare, you’ll find BoltShare familiar. This page is an honest look at where the two differ, so you can pick the right one for each transfer. It isn’t a claim that one is better at everything.
What the two have in common
- Live transfer, nothing stored. In both, the file streams from the sender’s browser to the receiver’s while both pages are open. ToffeeShare says it stores nothing online and that your files stop being accessible once you close the tab. BoltShare works the same way.
- No size limit. Because there’s no server copy, neither service has a reason to cap file size.
- No account, no install. Open the site, drop a file, share a link.
- The sender must stay online. This is the trade-off of any live transfer. If the sender’s tab closes, there’s nothing left to download from.
Where they differ
| ToffeeShare | BoltShare | |
|---|---|---|
| How data travels | Peer-to-peer over WebRTC | Your choice: Bolt Tunnel (relay) or Direct P2P (WebRTC) |
| Encryption | End-to-end (DTLS) | Direct P2P: end-to-end (DTLS). Bolt Tunnel: TLS to and from the relay |
| Strict office, school or mobile networks | Depends on whether a peer-to-peer route can be found | Bolt Tunnel works on almost any network |
| Recovering from dropped connections | Not documented | Reconnects and resumes from the last confirmed byte |
| Cost | Free, donation-supported | Free, ad-supported (why we show ads) |
Strict networks
The biggest practical difference is what happens when a direct connection can’t be made. Corporate firewalls, university networks and many mobile carriers (especially those using carrier-grade NAT) block the routes that peer-to-peer tools rely on. When that happens, a purely peer-to-peer transfer can sit on “connecting” forever.
BoltShare’s default mode, Bolt Tunnel, avoids this. Both browsers make an ordinary secure web connection (wss://) to a relay on Cloudflare’s network, and the relay passes each piece of the file along as it arrives. It never writes anything to disk. Since that’s the same kind of connection any website uses, it gets through networks that block peer-to-peer. In our own measurements, it’s also usually faster for people on mobile data.
Resuming
On long transfers, Wi-Fi blips and laptops changing networks are common. BoltShare’s receiver confirms what it has written to disk, so if either connection drops, both sides reconnect and continue from the last confirmed byte instead of starting again.
Where ToffeeShare is the better pick
We’d rather you use the right tool, so here’s when we’d choose ToffeeShare:
- You want end-to-end encryption with no settings to think about. In BoltShare you get that with Direct P2P mode, but the default Bolt Tunnel mode encrypts to and from our relay rather than end to end. ToffeeShare is peer-to-peer only, so you never have to choose.
- You’d rather use a site with no ads. ToffeeShare is funded by donations. BoltShare shows ads to cover the relay bandwidth.
Where BoltShare is the better pick
- One of you is on a work, school or hotel network, or on mobile data, and peer-to-peer won’t connect.
- You’re sending something large over a shaky connection, where resuming after a drop saves you from starting again.
- You’re sending a folder or many files and want them to arrive as a single ZIP. See how to send a whole folder.
If a transfer won’t start
Whichever tool you use, most failed live transfers come down to the same few causes: a blocked network, a sleeping laptop, or a phone that has paused the browser. Our guides to transfers that won’t connect and keeping a transfer running cover the fixes. For the technical side of peer-to-peer, see what WebRTC is and Direct P2P vs Bolt Tunnel.
