blixtOne trip, no custodian
The file goes straight from your machine to theirs — no upload-then-download detour, no copy resting on a third-party server after you hit send.
Comparison
Blixt vs Send Anywhere, Filemail & Smash
These services nailed one thing: sending a big file to someone who will install nothing. Open a page, drop a file, share a link — free tiers included. The trade is the route: your file travels through their cloud, on their limits, on their word about security. Blixt takes the direct route instead.
| Send Anywhere / Filemail / Smash | Blixt | |
|---|---|---|
| Direct, no middleman | Link sends travel through their cloud — the file rests on their servers | Yes — direct P2P; the file never rests anywhere in between |
| Speed | Two trips — upload to their server, then download — throttled both ways | One direct trip; QUIC + BBR with parallel streams |
| Size limits | Caps per send on every tier; bigger caps cost more | 500 MB per file on Free; uncapped per file on every paid plan |
| Resume after a drop | Varies — a failed transfer usually means starting over | Yes — MAC-protected block journal; only missing chunks are re-sent |
| Verifiable E2E security | “We encrypt your files” — you take their word for it | TLS 1.3 + fail-closed pinning, a 6-digit SAS you compare out of band, BLAKE3 per chunk |
| LAN / offline mode | No — their service must be reachable | Yes — same-network transfers with no internet and no server |
| Receiver needs only a browser | Yes — their core strength | Direct transfers need Blixt on both sides; bCloud share links are received in any browser, on any device |
| Mobile apps | Production mobile apps are available | Android Preview 0.1.0: Sideloaded debug APK; Android 10+, arm64. iOS is planned |
| Ads | Yes, on the free tiers | None, on any plan |
| Price | Free with ads and caps; paid ~$5–15/mo | Free $0; paid $5–50/mo flat |
Competitor pricing is approximate, from public pages as of mid-2026 — confirm current terms with each vendor.
Honesty first
Where Send Anywhere, Filemail or Smash is the better choice
For a one-off file to someone who will install nothing, they win. Nothing beats a website that just works: no app on either side, a free tier that covers casual sends, and polished mobile apps today. Blixt currently offers only an Android Preview 0.1.0: Sideloaded debug APK; Android 10+, arm64. iOS is planned. If the file is small, the deadline is loose, and the receiver is a stranger to software installs, use them and move on.
The case for Blixt
Where Blixt wins
Encryption you can check
TLS 1.3 with fail-closed certificate pinning, a short code both sides compare out of band, and BLAKE3 hashes on every chunk and the whole file. Not a promise — a procedure.
Drops don’t reset the clock
An interrupted transfer uses its tamper-protected block journal and re-sends only the verified chunks still missing.
No internet required
On the same network, transfers run fully offline with no server involved — something a cloud sender cannot do by design.
