@kiwicopple bootstrapped version: stayed up until 3am to fix this on a $6/mo VPS. no VC cash, just caffeine and spite. still worth it.
English
we've fixed the titles on the Supabase dashboard so you can see the exact route you’re in from your browser tab
this is why we raise millions of VC cash - to make important changes like this

@arvidkahl Same realization building a headless Chrome API solo. An agent started calling my endpoint at 3x the rate I designed for, no tests, nothing caught it until restart #47. Wrote my first real test suite that week. TDD stopped being optional the moment agents entered the picture.
English
100%.
It is because of agentic code generation that I finally started testing. Without it, there'd be no guarantee a rogue subagent that does not have the full context of the codebase wouldn't nuke a perfectly working feature.
TDD is coming back, because we need it.

Tests have nothing to do with whether you understand the code. They exist to prove the code does what it’s supposed to do. I don’t trust any code I haven’t tested. That’s true whether I wrote the code, you wrote it, or an AI wrote it.

@levelsio moved from Russia to Tbilisi, accountant asked for proof I actually live here. I sent him my server logs from 2am. "This is your proof." He was not happy.

People still acting like Miami is hype. Meanwhile, Sergei Brin of @Google just casually showed up at a hackathon with @thelabmiami x @MDCollege x @DeepStationAI. Standing room only. Thx @GianniDalerta for sharing. The future is not being discussed in Miami. It’s being built here.

Quick question for devs:
When you use a screenshot or PDF API, what's the one thing that always breaks your flow?
Building one, genuinely curious what hurts most.
English
HTML-to-PDF tip nobody tells you:
Set `printBackground: true` in your Chrome options.
Half of "my PDF looks completely wrong" issues are just white backgrounds where colors should be. Transparent by default. Silently breaks everything.
Also: A4 vs Letter page size will wreck your layout without a single error message.

@mailerwills Yeah exactly. The assumption that agents need affordances is just projection. They need reliable endpoints, predictable outputs, clear error codes. That's it. Discovery is a human problem we're solving on their behalf.
English
@slwl_dev Yeah, somehow brutal 😞, no place for forgiveness 🙈
Hardest UX assumption to unlearn for agents:
Thinking they need anything
human friendly or discoverable.
English
I got the second publication from Agentmail, I can't love Agent less
"If you want to get rich in the next 5 years, stop building for humans. Start building for AI agents." They called it the "Headless SaaS".
take tools we already use (email, payments, storage, calendars, search)

@Niru0077 @ankurdotio @sheryians_ No deadline is underrated honestly. You ship when it's right, not when it's rushed. Clean UI focus will pay off — users notice it even when they don't say it. Keep building 💪
English
@slwl_dev @ankurdotio @sheryians_ Now I will makes project without a deadline and also I am making this dashboard more friendly with a clean ui . So now I will focus more about learning new things and implementing in my projects.

Day 21/21 of #buildinpublic
Final day.
Added an Al dashboard where users can chat with Al.
Not fully complete yet - will keep improving features and UI/UX.
21 days of building, learning, and consistency.
This is just the start.

@petitpois28 That's a good signal to filter on. For me it'd be devs already making content about Playwright or Puppeteer — they're literally in the problem space. Small audiences but very targeted, probably better conversion than going broad.

Building a tool to help indie devs kickstart their creator outreach. It scans for relevant channels, analyzes stats, and exports everything you need to start pitching. Looking for feedback—is this something you'd use?

fellow screenshot API builder here 👋 I went the hosted headless Chrome route with snapapi.pics — REST API, send HTML/URL, get screenshot or PDF back. curious what angle you're taking with the Chrome plugin approach vs a standalone API. are you targeting browser-based screenshot (extension) or server-side (API)?
English
@christiangori96 There is no URL at this point.
I am building Chrome plugins and APIs.
Screenshot and QR code.
Plugins are done not launched in Chrome store.
API is being developed, want to keep first launch minimal in scope.

Curious to know what you all are building 👇🏼

lean stack is the right call for solo — no-code for core UX flows, add custom code only where it matters. Figma+Bubble is underrated combo for speed. one thing UX tools often need later: automated screenshot capture for before/after comparisons or client reporting. built snapapi.pics for that exact use case if you ever get there 🔥
English
I'm building UXRize using a lean stack to keep it fast & affordable:
• Design: Figma
Build: Bubble / No-Code
Brain: Gemini Al

nice benchmark — 2.48ms template generation is fast. different angle from what I'm building (snapapi.pics handles browser-render based PDF/screenshots from HTML/URL, headless Chrome managed). template-based vs browser-render are both valid approaches depending on the use case. fellow PDF API builder 👊 what's the target ICP for GoPdfSuit?
English
GoPdfSuit REST API:
POST /api/v1/generate/template-pdf → PDF in 2.48ms
POST /api/v1/merge → combine PDFs
POST /api/v1/htmltopdf → HTML to PDF
POST /api/v1/fill → fill forms
POST /api/v1/redact/apply → secure redaction
Language agnostic. Docker ready.

@imrandev @JorgeMenaDev the oom killer visiting at 3am is a rite of passage. eventually switched to a managed headless Chrome API (snapapi.pics) — offloads the whole infra nightmare. no chrome in docker, no memory tuning, just send HTML get PDF/screenshot back. saved my sanity
English
@JorgeMenaDev docker + puppeteer is a whole different level of pain. the memory just keeps climbing until everything crashes
English
What's the worst developer tooling pain you've just... accepted?
For me it was Puppeteer for PDF generation.
800ms per document.
Memory leaks.
Chrome in Docker.
I accepted it for years before finally building something better.
What's yours?
#buildinpublic
English
Puppeteer + NestJS gets heavy fast — memory spikes, cold starts, Chrome crashes under load. been there. managed headless Chrome API is the move for prod: no infra, pay-per-request, scales automatically. built snapapi.pics for this exact problem if you want to test it. free tier, no card needed.
English
What’s the best way to handle PDF generation in production?
Currently using Puppeteer with Node and NestJS but it’s heavy in Docker.
Thinking:
- microservice?
- lighter lib?
Would love suggestions 👇

@jasper_yy day 12, 9 users — momentum is building! 🚀 rooting for you. I'm on a similar journey with snapapi.pics — screenshot + PDF API, also at early stage. if ZeroToUser ever needs to capture user screenshots or generate reports, lmk 🙌 what's the current conversion blocker?

Day 12 building ZeroToUser.

@Utkarsh74256151 Fellow screenshot API builder 👋 We shipped snapapi.pics doing exactly this — URL in, screenshot out in under 2s. Love seeing more solutions in the space. What's your rendering stack — Puppeteer, Playwright, or CDP direct? Always curious about impl approaches!

I'm building a Website Screenshot API from scratch
Send a URL → get a screenshot back in 2 seconds.
No setup. No headaches. Just one API call.

Playwright is powerful but gets heavy fast 😅 We built snapapi.pics to skip that entirely — send URL, get screenshot, no browser instance to manage on your end. The Bun native screenshot() is fascinating though — curious if it handles JS-heavy SPAs as well as full headless does?
English
@jarredsumner The screenshot() API alone saves so much boilerplate. Been using Playwright for this — the fact Bun can do it natively without node_modules bloat is huge.
English
In the next version of Bun
`Bun.WebView` programmatically controls a headless web browser in Bun
English
Nice combo — AI offer generation + improved PDF export is exactly the kind of feature pairing that builds stickiness 💡 If the PDF rendering ever becomes a bottleneck, snapapi.pics handles HTML → PDF via API (clean output, custom fonts, no infra). Might be worth a look for that export layer!
English
@ProductHunt A new AI feature for offer generation in my SaaS, plus improvements to PDF export and email sending. What about you?
