GPT Image 2 Model seems good

Prompt: use manga illustration of person relationship of A Tale of Two Cities

@levelsio @brian_lovin That's so true.
Migrated from AWS to Hetzner last year and my sever costs reduced from $800 to $20 for a project

AWS ElastiCache costs alone can buy me 20 Hetzner server where I can install redis in Docker container and use for free.

@kail_designs looks amazing！

[Robert Chang @cht0001]

@ClaudeDevs You are absolutely right!

The Android version isn't even out yet.

The ecosystem is DAY ZERO.

Stop scrolling. Start building.

Dear founders/developers

XChat launches today.

While everyone's debating if it'll beat WhatsApp, I asked Claude what could be the opportunities there. Here are 10 businesses you could consider to build on it RIGHT NOW:

[Robert Chang @cht0001]

10. Mini app framework — WeChat makes billions from Mini Programs. Build the framework before X does.

[Robert Chang @cht0001]

9. Webhook bridge — Let any backend trigger XChat messages. This is how Slack's ecosystem started.

[Robert Chang @cht0001]

8. Expense tracker — When X Money goes live, people will need spending insights inside chat.

[Robert Chang @cht0001]

7. Booking bot — Hair salons, dentists, consultants. Clients book via DM. No app download needed.

[Robert Chang @cht0001]

6. AI sticker store — Generate custom branded sticker packs with AI. Every messenger spawns a sticker economy.

[Robert Chang @cht0001]

5. P2P marketplace bot — Local classifieds inside encrypted chat. X Money + XChat = built-in payments.

[Robert Chang @cht0001]

4. Group analytics dashboard — 481-member group chats need moderation + engagement tools. Discord analytics but for XChat.

[Robert Chang @cht0001]

3. CRM bridge — Sync XChat convos into HubSpot/Salesforce automatically. Classic picks-and-shovels play.

[Robert Chang @cht0001]

2. AI support agent — Connect any knowledge base, auto-reply to customer DMs. Intercom charges $50-100/seat for this.

[Robert Chang @cht0001]

1. Commerce bot platform — "Shopify for XChat DMs." No phone number needed. 500M users. Let merchants sell directly in chat.

just opened stripe and saw A$28.31 sitting there
I vibed-coded a random site like 6-7 months ago, literally forgot it existed, never marketed it, never touched it again

188 clicks. 5k impressions.
one single payment.

the graph looks like it woke up from a coma and decided to pay my coffee tab

anyone else got a zombie side project that randomly sent them money?

drop your ghost site stories below lmao

Me staring at it like it’s my last cigarette at 2am

“Should I save it… or just… one more hit?”

@dhh Thank you, sir! I switched my little projects from AWS to a VPS after following your suggestions, and my server bills have dropped from $800 down to just $80 😆
