CAPTCHA made with Jev

I rebuilt CAPTCHA with Jev

The browser measures how you fill in the form. Server turns that into a few plain sentences, and Jev decides: person or bot.

Check out this diagram!

[Jarek @jarekceborski]

I tried explaining LocalCan tunnels to non-developers. Does this diagram make sense? I’d love your feedback before adding it to the LocalCan website.

LocalCan 3.2 is here! Adds a design feedback loop for humans and agents.

Snapshots can now collect feedback. Share a link, and others can pin comments right on the page.

Then hand it to your coding agent: it reads the comments, fixes the design, replies, and resolves. If you build prototypes with AI, this is how you get real feedback on them.

[Jarek @jarekceborski]

so I guess @LocalCanApp is becoming a designer tool

Comments are coming! 💬

[Jarek @jarekceborski]

Leave a comment on a prototype, the agent implements it. That's what I'm aiming for with @LocalCanApp.

Snapshots already let designers push a prototype to a public URL and collect feedback. Soon, the feedback will be a comment sitting on the page itself.

So the loop goes like this: the client leaves a comment, you or your agent picks it up, makes the change, and republishes the Snapshot. Same URL the whole time.

Let me know if you'd like early access!

How to share design prototypes using Snapshots:

[Jarek @jarekceborski]

I stopped sending Figma links, prototypes are real code now.

The problem was never designing, it was sharing. Deploying for one review round is a lot of ceremony.

So I share the thing running on my laptop instead. Public URL, live, auto refreshed with my edits. When I close the laptop, a Snapshot keeps the same link alive.

How are you sharing work these days?

(@LocalCanApp is mine, bias disclaimer applies)

[LocalCan @LocalCanApp]

@zenorocha Something like tunneling or hosting?

Snapshots are now available on the Free plan!

Deploy a static copy of your app to LocalCan so the link keeps working when you are offline - comes in handy when you want to share your work with folks in a different time zone.

3.0 stable release is now live!

[Jarek @jarekceborski]

After 10 betas, I released @LocalCanApp 3.0 stable!

Quiet launch for now: it’s midsummer, people are vacationmaxxing, and too many users were confused by the new features not being available when they downloaded v2.7.

In the meantime, I’m prepping for a launch event in a month or so, starting with some landing page updates.
