Single maker launch. --- ## First-hour checklist **T-minus 1 hour (before launch):** - [ ] Confirm the home page renders correctly - [ ] Confirm the embed page works - [ ] Confirm the donate page works - [ ] Have the press-pitch email draft ready to send - [ ] Have the X/Bluesky thread ready to post - [ ] Have 3 supporters lined up who will comment in the first hour **T-zero (00:01 PT):** - [ ] Submit the post on Product Hunt - [ ] Post the X/Bluesky thread - [ ] Post the first comment on the PH post (the "Author here" intro) - [ ] Send the press-pitch email to the 3-5 journalists on your list **T+30 minutes:** - [ ] Reply to every comment - [ ] Cross-link from the maker Twitter/Bluesky **T+2 hours:** - [ ] Check the post for any comment that needs a fast reply - [ ] Post the "first hour update" comment ("Author here. We\'re at #X on the leaderboard, here is what we\'re working on next...") **T+24 hours:** - [ ] Send a "thank you" comment on the PH post - [ ] Record the metrics in `INCOME.md` --- ## Maker comment (the first comment on the PH post) > Author here. A few things I should have put in the main post: > > - The site is **non-commercial.** There is no business model. There is no display ad inventory, no email list, no newsletter, no upsell, no pop-up. The donate link has been live for 9 months; total donations received: £34.50. (The third-party scripts on the site are Google Analytics, for measurement, and three.js / cannon.js / the YouTube IFrame API on the specific tool pages that need them. None are advertising.) > - The number **is honest and checkable.** There are 1,424 separate tool pages and a `cards.json` file with an entry for each of them. The count is exposed at the top of `/tools.html`. > - The **no-display-ads claim is verifiable.** View source on any page. You will not find an ad slot, an ads.txt file, an ad network script, or a sponsored-content block. The whole markup is the tool and its text. > - The site is **open source.** https://github.com/mrpr0phecy/mrpr0phecy. The repo is about 92 MB in total, most of it a photo library that two of the non-tool pages use. > - I am **one person**, based in Luton, UK. I work on this in the evenings and weekends. > - The thing I am most proud of is the **"How mortgages really work" guide** at https://www.themostusefulsiteintheworld.com/guides/mortgage.html. The bank\'s calculator never tells you the total interest. The guide walks through it. > > **If you only click one thing on the site**, that guide is the one. > > **If you want to embed a tool** (e.g. on your own site or in a school newsletter), `/embed.html` gives you a one-line iframe for any of the 1,424 tools. > > Happy to answer questions. I read every comment. --- ## The PH-specific tactics that work in 2026 1. **Engagement > raw upvotes.** Product Hunt\'s algorithm in 2026 weights the *number* of comments and the *quality* of the discussion. A 50-comment post with thoughtful replies ranks higher than a 200-upvote post with no comments. Spend the first 2 hours replying to every comment with a substantive answer. 2. **Hunters, not just makers.** Get a hunter (someone with a good PH reputation) to submit the post instead of submitting it yourself. Posts with hunters get 2-3× the page-1 visibility. Ask a maker friend with a 100+ follower count to hunt it. 3. **Avoid the "AI" trap.** Don\'t call it "AI-powered" in the tagline. PH\'s audience is allergic to the word. The tagline is "1,424 free browser tools" — no buzzwords. 4. **Don\'t launch on a Friday or weekend.** Tuesday, Wednesday, or Thursday only. 5. **Don\'t launch on a day with a competitor.** Check the PH calendar the day before to make sure no comparable product is launching the same day. 6. **Stagger HN and PH.** If you\'re doing both, launch HN first (Tuesday), then PH 48 hours later (Thursday). Doing both the same day splits the launch energy. 7. **Don\'t ask for upvotes.** Asking in the post gets the post downranked. Asking in a comment is fine *if* you have given the comment a real, substantive update first. --- ## What to record after launch After 48 hours, record in `INCOME.md`: - PH upvotes (target: 200+) - PH comments (target: 30+) - PH rank at end of day (target: top 5 of the day) - PH follower gain (target: 100+) - Referral traffic from producthunt.com (target: 5,000+ sessions)
