No money. No seat. It goes on your record — and in 28 days reality settles it.

Dev. Launched 11d ago on Product Hunt, picking up 7 votes. Today, it's live, but nothing on the site has changed since we started watching.
Moving right now. The clock only starts when a launch goes quiet.
We check this site every day, ourselves. A founder can post “still working on it” — a claim like that doesn't price. What we price is what we can verify from the outside: evidence, not announcements. The real question isn't “will this be huge?” — it's “will they still be moving in four weeks?”
The market viewHow this launch is priced and ranked in our league — the investor side of the page.
ranked by the reality anchor, not the market price
It launched on Product Hunt with 7 votes. It also showed up on 1 other board — but didn't place well enough on any of them, so none of them add to the price. Listing on twelve directories is free; placing well on them isn't.
No matter how much money goes in. There is no pump here — you can't make yourself right by buying more. The line only moves on things that actually happened: an award, revenue that grew, a new platform, code that shipped — or silence.
1 quiet day in between are left out — nothing happened on them. A launch that goes quiet eases down a little at a time — never a cliff you could have run from the night before.
Daily tracking just started for this launch — the first point is on the board. A second reading lands with tomorrow's run, and the curve builds from there.
How the launch is moving on its own board, day by day — the crowd's attention.
A flat line is normal: votes stop within a day or two of launch, on every board. What's unusual — and what actually counts — is a launch that keeps pulling votes long after its day is over.
About
InboxTap is a free, open-source SMTP capture server and test SDK for signup verification, password resets, OTPs, invitations, and other email flows. Run it locally, point your app to localhost, and let your tests read the real link or code. Each test gets an isolated inbox, so parallel runs do not mix messages. Nothing is delivered externally. Works with Playwright, Vitest, Jest, Bun, and Node 20+.
Where it launched
2 platformsThe board it did best on sets the price. Every other board only adds to it if the launch also placed high on that board too — because just showing up somewhere isn't an achievement. Listing on twelve directories is free; placing well on them isn't.
