I inspected the HTTP requests and this is absolutely not E2EE. Clipboard contents are POSTed as plaintext to <a href="https://www.quickclip.space/api/encrypt" rel="nofollow">https://www.quickclip.space/api/encrypt</a>, and can be decrypted later via <a href="https://www.quickclip.space/api/decrypt" rel="nofollow">https://www.quickclip.space/api/decrypt</a><p>Encryption appears to be in the openssl "Salted__" format (and base64 encoded). I can't infer the actual encryption algorithm configured, but it's an <i>unauthenticated</i> block cipher with 128-bit blocks, presumably in CBC mode, padded with PKCS7.
Also, uploaded images are publicly reachable in plaintext and without auth: <a href="https://wjynmjluabqwqhtdxbtl.supabase.co/storage/v1/object/clipboard-images/491a3113-b371-4680-a42b-26a517f1ae38/1767194245874-Screenshot_From_2025-12-24_07-44-29.png" rel="nofollow">https://wjynmjluabqwqhtdxbtl.supabase.co/storage/v1/object/c...</a>
For those of us on Linux, I've built clapboard - a lightweight clipboard manager that uses whatever dmenu-like system for GUI, and plain files as a storage backend. Because all the history is just files, you can easily sync it between devices with a tool like syncthing. Probably a bit more slower than 0.1s though!<p><a href="https://github.com/bjesus/clapboard" rel="nofollow">https://github.com/bjesus/clapboard</a>

KDE Connect does that in LAN. Clipboard sync, file transfer, contacts, calls, remote control, etc.
Came that for that, how is this different (not necessarily better) than KDE Connect which I already use daily?
And you can do it over any network if you pair it with tailscale. Tailscale + KDE Connect is such a time saver.
I did something similar with Claude code, I did not write a single line of code and it’s hosted on cloudflare workers. With the free tier it’s enough for one person (and I feel safer to own and host my private data). Works beautifully.
Your website does not show how it works, no screenshots, it would be better with it
Same. I vibe-coded a real-time notepad thing with optional E2E with CC over a weekend. Not going to plug it unless someone asks me to, just pointing out how easy this is nowadays.
Thanks for your suggestions. Would work on it
Cool. I just wouldn't use it at all in its current form without more information on how you handle my data.<p>Why should users trust you?
Yeah fair point. QuickClip does store data in database, otherwise syncing between devices not possible. But here is how it works:<p>- Data is encrypted when sending and also when sitting in database.
- Stored only so your devices can fetch it, not for me or anyone else.
- When you delete, it’s gone. I don’t keep logs of clipboard stuff.
- I don’t look at your data, only your devices can see it.<p>I know trust is big thing for clipboard app. I’ll write small “how it works” page so it’s more clear. Appreciate you asking this, makes sense.
Where are the keys stored? If you encrypt the data but just have the keys in another database table, I don’t really see the point of having it encrypted at all.<p>I agree with others. I wouldn’t use this unless I trust how you’re handling my data security. All sorts of highly sensitive passwords and security keys hit my clipboard.
Your footer “no rights reserved just kidding” is not helping with trust building either.
So I just wanted to take a moment and say nice work I have a solution that works for me at the moment, although I should check if it's e2ee, but this is a great example of a simple SaaS that could really catch on and meet the niche needs of users. I like the design, I like the implementation, and I really like the price. Everyone and their 3rd cousin charges $5/month for for simple functions which I usually just pass on but yours is a great price point for the job.<p>Will definitely repost on social media!
The website does not show anything on how the product is used, which is kind of important for me as a potential customer. Especially if it's going to be effectively handling my copy/pasting of sensitive information.<p>Does it use some client, what do I need to install on my devices (if supported) and what permissions does it need etc? Instead I'm greeted by a login page.<p>It's not transparent enough for me how the product is used before signing up and that's a huge turn off.
Funny, i want Apple to STOP synchronizing my clipboard between devices. I'm doing different things on them and I don't need the last piece of code on my desktop to paste in the 'where do we go out tonight' chat on whatsapp on my phone.<p>If I do want to move some info i'll message it to myself thank you.
I sync my history between Fire/Waterfox on my phone and laptops, and since almost anything I wanna copy and paste is in the browser, I just open whatever it is from Other Devices. For files or images, I use LocalSend now for everything.<p>Which is not to say there's not a big use case for this, but speaking only for myself, it's not a pain point. But it looks cool!
KDE Connect works fine for me and does more than clipboard (files, mouse sharing etc.).
Copy API keys<p>I would add examples how data encryption works. This is so sensitive topic. But if you explain it nicely, people could use the service.<p>I would add FAQ. Boxes seem like I can read more but I can’t.
Closed source ? i mean thanks for the project but not for me
i know a gemini 3 site when i see one lol, looks good tho! Does this work if you copy an image on your phone/laptop, will it sync to the other device?
> i know a gemini 3 site when i see one lol, looks good tho!<p>Ha I thought the same. I created a website that's also in this neo-brutalist style and it has the same marquee.<p>This reminds me of when everything used to look like default Bootstrap.
Yes, It works smoothly with texts and images both
> For Developers<p>Would you mind sharing the source code?<p>> Copy API keys<p>...yeah, I think that'd be a hard requirement. I don't think there is value in a cliboard-as-a-SaaS that is not self-hostable or even auditable.<p>I think you are putting the cart before the horse and putting your users at risk by integrating credit card payments before sorting out the basics.
I forgot that this was a problem for some. I’ve been op iPad iPhone and macOS for too long it guess.
> Would honestly love to hear, how you move stuff between devices today<p>In cases where iOS/macOS misbehave, I use (IMAP) email without sending anything:<p>- create new mail message<p>- paste text or add attachments<p>- save as draft<p>- open draft on other device<p>- copy out the data<p>- delete draft<p>Works reliably for not-too-large items
