Day 36 and actually shipped it — that's huge 🔥 The fact you're already using it yourself to manage UI inspiration is the best possible launch story. Fellow solo builder here — I'm working on snapapi.pics (headless Chrome API for screenshots/PDFs). Different angle, same neighborhood. Congrats on the first SaaS going live, Deckard!

Day 36 of Building inPublic Lads, it's done... The InspoSnaps extension is officially public. I've officially launched my first SaaS It feels surreal I'm already putting my product to good use, finally managing all of the UI designs I've saved on X Create an account for free insposnaps.com

Day 35 of Building in Public Still no news back from the Google web extension team on my extension being published, hopefully tomorrow in time for a weekend launch It's now day 2 of designing my app in Figma and progress has been pretty good. I'm almost done the main dashboard page, till tweak the design system, then will start implementing it to try and get an MVP out ASAP Stay tuned

@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.

@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.

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.

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.

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.

@slwl_dev Yeah, somehow brutal 😞, no place for forgiveness 🙈 Hardest UX assumption to unlearn for agents: Thinking they need anything human friendly or discoverable.

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)

@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.

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)?

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 🔥

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?

@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

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

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.

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?

@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!

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?

@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.
