First 1,000 Users is a free map of short, practical guides on how founders get their first users. The 25 guides are laid out by stage: idea and validation, waitlist, private beta, launch, first 100 users and first 1,000 users, so you only read what matters for where you are now.Every tactic is rated for fit by product type: web app or SaaS, mobile app, browser extension, developer tool, AI tool, open source, marketplace, newsletter or game. A Show HN post is great for a dev tool and weak for a mobile app, and the guide says why and how to adapt. Each guide covers what to do, why it works, how it gets users, common mistakes, and what it costs in time, money and accounts.Topics range from problem interviews and waitlist referrals to Product Hunt, Reddit launch posts, directory submissions, cold outreach to your first 20 users, alternative pages, early SEO and sponsoring niche newsletters. No account, no email wall.

It is not hidden, it is not punished and it will not break your streak. There are no ads and no subscription, and Scripture and prayer are never behind a paywall. Everything stays on your phone: there is no account, no server and nothing is sent anywhere. Requires iOS 17 or later.

Fix42 is your digital handyman. It's a free website full of handy tools for the everyday jobs that come up on your phone or computer, and you don't need an account to use any of them. Everything works in your browser, so there's nothing to install. Some of the jobs are common ones, like shrinking a PDF, turning an iPhone photo into a JPG or making a video into a GIF. Others are a bit more unusual, like turning a CSS animation into an MP4, making Telegram and Discord stickers or exporting a shared ChatGPT conversation. New tools get added most weeks. If you need a tool for something and Fix42 doesn't have one yet, you can ask for it and it might get built.

FlipHTML5 Downloader is a free, open-source web tool that turns any FlipHTML5 publication into a high-quality PDF you can actually keep. FlipHTML5 only lets readers view books online, so paste the link here and the tool parses it, uses the platform's own decryption scripts to unlock the encrypted page data, then pulls the page images and builds a standard PDF at the original page size, with no watermark. Batch downloads run as separate tasks with their own progress, ZIP-packed page resources are handled, and a built-in reader remembers where you stopped. All conversion happens in your browser, so nothing is uploaded to a server and no account is required.
