Thank you, and great question. In my experience, big companies have way more strategic priorities than two guys who just want to build something useful. We didn't leave to build exactly this, but a few things came together organically from past projects, including our work at Dropbox.
Right. We don't provide storage. Blip is designed to be the fastest way to send things to your devices and to other people in real time, without waiting for uploads, sync, or managing shared links.
That's right. We actively manage load across our relay network to ensure good performance, but we'll prioritize business transfers during peak times. We don't artificially limit the client, but P2P connection speeds can sometimes be affected by router configurations and ISP routing. For example, some ISPs route P2P traffic through slower paths, which can introduce variability.
Hey! Blip co-founder here. We didn't expect to show up on HN, but really grateful to OP for sharing Blip. Here's a little bit more about it.
We've built Blip because it's still hard to send original quality photos, videos, and large files to your devices and to other people on the internet. We’re designers and engineers, so our goal has always been to keep the product super simple on the surface, but really fast and powerful underneath.
Blip works in a peer-to-peer way at the UI level: you pick the device or person, and Blip takes care of the delivery. Transfers go directly over WAN whenever possible, and fall back to relays when needed. The idea is to send in one click, skipping the usual dance of moving files through cloud drives and managing shared links.
Under the hood, Blip is optimized for large media and data transfers. It supports full-speed acceleration, resumable progress, and we're rolling out E2EE across all clients to ensure sensitive business data remains secure. Many creative pros and teams already use Blip in their daily media workflows.
We don’t monetize data because it doesn't align with the values of our creative and technical users. Instead, we run on a simple donation and subscription model that lets you support the product and use it without limits, quotas, and frustrations. Our goal is to make file transfer feel invisible.
Hey, really appreciate such thoughtful reply. I’ll address your questions while explaining our design decisions and how Blip works.
We set Blip to use email addresses because we wanted to make it convenient for people who are less tech savvy and for business customers who need to quickly find and know who they’re sending files to. If you sign in on another device, all your other devices and recent people are just a click away—so you don’t need to set up or sync that list by yourself.
Blip is a local-first app in the sense that it works with files on your devices, but the interactions are server-driven, letting you negotiate transfers with your devices and other people, no matter where they are. When transferring files, we try to connect devices directly over IP, but when that’s not possible (and it often is not) we relay files over our servers. We use TLS 1.3 to encrypt files in transit. When devices are connected directly, we use mTLS for an even higher level of security. We plan on adding full E2EE in the future.
We care a lot about speed! We don’t throttle transfer speeds when devices are connected directly. Sending files on home Wi-Fi should be as fast as possible, as long as devices can ping each other. Reduced speeds only apply when using our relay network. If demand is high, business customers get priority to ensure their work is delivered on time.
Our business model is still very much evolving. Our main goal was to structure it in a way where people who benefit from Blip commercially should be supporting it the most. We considered a licensing model, but Blip relies on infrastructure maintenance and continuous development, so we need everyone on the latest and most secure version. We decided to make a clear distinction between community and business users, because we learned there’s more demand for speed at work. Of course, if community users start experiencing slow speeds (in practice, this hasn’t been the case), we’d love too bring this to personal users to. One way is for one-time donations to provide high-speed data boosts. Since personal users don’t require extra support and business features, pricing can be more affordable.
All that said, it’s so good to know that speed matters! Our goal has always been to make Blip the fastest way to send files.
Thanks again for the feedback, and for the heads-up on the typo—already fixed! :)
