UI for humans to do the work by clicking will be gone. UI for humans to understand data, numbers, and status will stay. UI for humans to command agents is emerging.

LocalCan™ has a Free plan now. No warning page for your visitors. Sign up with an email, get a Public URL on trylocalcan. com. No card. Why it's shaped this way:

trylocalcan.com

trylocalcan.com — temporary preview URLs by LocalCan

Links on trylocalcan.com are temporary preview URLs developers create with LocalCan to share work running on their own computer.

"Publish this prototype and put a password on it." That prompt now works from inside Claude/Codex/Cursor etc. The nice thing about it is that the full cycle is now 100% agent-driven: Design → Build → Publish → Share. No dashboard tab, no dragging a folder anywhere.

Happy with how this panel turned out. Select a Public URL and you see the actual route: LocalCan's network on top, your machine below, tunnel in between.

Webhook debugging used to be: trigger it, dig through logs, copy whatever you find, paste it into an AI chat, hope you grabbed the right request. Now the agent just reads the traffic itself. "A webhook failed, find out why" and it pulls the exact request and response LocalCan captured.

What I really like about AI is that at least half of my day is spent making judgment calls instead of doing boring, tedious work. And that share keeps growing.

Jarek @jarekceborski.com · 15/06/2026

I haven't designed a website for some time, and I forgot how long it takes. The new @localcan.com landing page is coming together nicely, and I can't wait to finalize it and launch. BTW, let me know if you have any feedback!

I put together a tutorial on OAuth 2.1 for MCP servers. Fully working end to end against a real auth server, with every gotcha I hit along the way.

Building an MCP server? I wrote a blog post for you:

Never imagined I'd give an AI agent access to LocalCan CLI, ask it to use it, and ask about the experience and provide feedback. Wild!

npm supply-chain attacks keep happening, so I hardened all my repos and wrote up the checklist. Mostly two lines of config. Do it before the next one.

Jarek @jarekceborski.com · 12/05/2026

This could be the best or worst business decision: LocalCan is going subscription-only very soon (don't worry, existing perpetual licenses will keep working).

Jarek @jarekceborski.com · 11/05/2026

Large projects with AI aren't a code-writing problem. They're a context-management problem (or really, an attention problem). I wrote a blog post about how I use Claude Code across a 6-repo, multi-language codebase. Link in comments.

Quietly the biggest thing I've shipped in 3 years. A full rewrite - from pixels to infra. A real CLI, a global edge network, Linux support. The version of LocalCan I always wanted to ship. Beta out today 👇

Jarek @jarekceborski.com · 20/04/2026

Sneak peek of @localcan.com 3.0, super excited about releasing the beta soon-ish! It includes CLI, multi-region infra, YAML-driven config, and added Linux support. Fully rewritten in Go (app + infra). From my tests, the performance gains are huge, especially for folks outside the EU.

The new Geist Pixel font is really nice! btw, the blog post: www.localcan.com/blog/testing...

What shocks me when comparing Kerlig vs. LocalCan is the revenue per website visit: Kerlig = $0.16 / visit LocalCan = $0.86 / visit and I think Kerlig needs to pivot!

3D printing was fun (circa 2020)

Jarek @jarekceborski.com · 25/09/2025

Developers need great tools with top DX, period. This is as true now as it was back in 2023 when LocalCan only allowed publishing .local domains on the local network. TCP tunnels open a whole bunch of new possibilities when developing: K8s clusters, gRPC services or exposing local database Enjoy!

huge milestone today – it all started as side projects on my laptop – now my apps have crossed $100k in revenue! I've made several pivots in my life, but this one is definitely the most challenging, ambitious and rewarding so far now back to work

How do you sharpen your skills in a new field? Here is my example: I built a free webhook tester, Webhook.Cool, that now runs 100% on autopilot and has just crossed 25M requests, with traffic from Google only growing! It was a fun little exercise that taught me about:

weekend project: Upgrade 12GB Postgres DB (Docker) from version 12 to 17 → Done ✅ I thought I'd write a blog post about it, but I checked the search volume and it seems I'm a rare individual who ever searches for that, so no.

Finally added Custom Actions to the Help section in Kerlig, using JavaScript in prompts is pretty cool! 👇

I have fully switched to Gemini 2.5 Pro with all my tasks. It handles everything from customer support to coding, summarizing, and proofreading. Both in English and Polish.

A quick, technical demo, if you are curious – getting content from Safari, Notes and Slack to @Kerlig.com. Currently in JSON, as the initial step. I'm using Accessibility API and Swift.

Random thoughts 9 minutes explaining why Jony & Sam are best buddies, why? Steve Jobs created enormous momentum that lasts to this day, but won't last forever.

Jarek @jarekceborski.com · 21/05/2025

I've been scratching my head recently about how to easily use content from other apps in @Kerlig.com to give AI the context for meaningful chat, and not just take a "screenshot," but actual content. Here is the idea. What do you think?

Jarek @jarekceborski.com · 19/05/2025

faster workflows! 💨

Jarek @jarekceborski.com · 16/05/2025

I've been exploring lots of new stuff for Kerlig, for example capturing content from other windows as content – useful in browsers, especially when you see things as a logged-in user – think Notion, YouTube transcripts & comments, Twitter, LinkedIn etc. Really cool, I already have a POC for that.
