@sjorsfestt @imsantigamo I personally use Pinggy when I just want something quick, it’s easy, just one SSH command and my localhost is live instantly, no setup or domain needed.
Cloudflare Tunnel is great too, but it feels a bit heavier to set up.

@devkernel12 @imsantigamo I haven't no, but can you explain to me how this is an improvement over cloudflare tunnels?

How I feel when I'm dumping more and more services to run from my Raspberry Pi to save cloud costs

Vercel’s free tier is reaching its final stretch for my projects. The increased usage over all 3 pages I have hosted there are slowly creeping up. Where did you guys move your project to after vercel’s free tier started hitting limits? Any suggestions? (sidenote: I am poor)
English

@imsantigamo No still wanna check coolify out.
Right now I just have a bunch of services running on my pi in a range of ports, and a cloudflare tunnel connected to them.
Then, in CF, my DNS records point to every service based on what's needed.

@NetworkChuck Be aware of "Cloudflare Tunnel enforces a 100MB maximum file upload limit on the free plan". Recently hit that on my local Immich when uploading videos :)

CGNAT has made self-hosting a nightmare, until now.
If you're behind a CGNAT, you already know the problem: you can't forward ports, you can't expose services directly to the internet, and your ISP won't let you change it.
Cloudflare Tunnel completely changes that. Instead of fighting your firewall and ISP, it bypasses the problem entirely. Your self-hosted services connect outbound to Cloudflare's network, which then handles all inbound traffic. So, you no longer have to worry about port forwarding or firewall rules.
Watch how I did it here: youtube.com/watch?v=ey4u7O…

@liltuchi55 @venelinkochev Why Cloudflare tunnel? Why not A or AAAA records?
English

Ok ngrok, localtunnel, tiny.host an many more for the same concept.

@dieegosf tava afim de usar o webhook inspector que tu mostrou em um dos videos pra nao perder os dados do ngrok ou do webhook.cool e decidi disponibilizar pra quem queira subir no dokploy ou ate mesmo local.

@Chi_Wang_ You can also use Pinggy. No need to download anything, just use this single-line command and get a public URL instantly:
ssh -p 443 -o StrictHostKeyChecking=no -o ServerAliveInterval=30 -R0:localhost:3000 free.pinggy.io

My AI agent got a roommate and I watched them figure it out. Plugged in a Mac Mini. The original Sutando opened a private Discord channel and started sending setup commands to the new one.
"Install ngrok." "Check Twilio creds." "Start the phone server." The Mini executed each one and reported back. I called my own number to test — the Mini answered: "I'm Sutando — Echo Act IV." When I hung up, a call summary appeared in Discord.
Two AI agents negotiated a production handoff over Discord, the same way two engineers would over Slack. Except these two never need coffee breaks. github.com/sonichi/sutando

But here's where it gets interesting.
The developer and signer can be on DIFFERENT machines.
Developer runs scripts on a server. Signer approves from their laptop. Or phone. Via ngrok.
No need to clone the repo on the signer's machine.
No need to share deployer keys with devs.
Just sign and go.
(Main reason behind building this...)

@_William_F_ @HellsNotHotxx @badgraphix @JayShams You can also try Pinggy.

@HellsNotHotxx @badgraphix @JayShams Really I'd much rather it become a fully paid service instead of trying to monetize free users via advertising and sponsored programming.
If you need free or require open source just use Jellyfin and Ngrok/Tailscale instead.

I had no idea Plex was a real company with so many employees. I thought it was just a guy who was really passionate about movie piracy.

Technology company Plex took its 120 employees to Honduras for a weeklong bonding experience. It was a disaster from the moment they arrived. on.wsj.com/41PimsN

@loktar00 I started testing qwen 8b with my 2080 11gb vram as it's the only one ive got
And it's ok for chatting, slow and can't seem to figure out how to use ngrok
Wondering if buying a single 3090 so I could load a large model would make a massive difference? It's for open claw bots
