Priced 200 at IPO on Jul 16. The curve starts building with the next run — Jul 17, 2026.
No money. No seat. It doesn't move the price. It goes on your record — and in 28 days reality settles it.
by reality anchor — the price money can't pump
Analytics. Launched 17h ago on PeerPush, where it placed #78. Today, it's live, but nothing on the site has changed since we started watching. It's anchored at 200 pts.
It placed #78 on PeerPush with 4 votes.
A launch's opening price comes from where it placed on its own board, normalised across all 12 platforms we watch. That's deliberate: #1 on a small board beats #40 on a huge one. It's how a launch nobody saw can still be worth more than one everybody did.
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.
Moving right now. The clock only starts when a launch goes quiet.
We fetch this site every day and hash what's on it. A founder can post “still working on it” — but if they actually shipped, the page changes. That's the only claim we price: evidence, not announcements. The real question isn't “will this be huge?” — it's “will they still be moving in four weeks?”
The story so farEVERY MOVE, AND WHY▾
Repriced every day, no cliffs. A launch that goes quiet bleeds a little at a time, so there's never a drop you could have run from the night before.
Momentum on its boardDOESN'T MOVE THE PRICE▾
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. This is the crowd's attention — it does not move the reality price. Only verifiable outcomes do.
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
Bosun is a native macOS menu bar app that gives you instant visibility into everything your Mac has open to the network, without touching Terminal or Activity Monitor. I built it after losing an hour tracking down which of six Docker containers was squatting on port 5432. Turns out lsof and Activity Monitor show you a port, not what's actually reachable on your machine right now. Every developer running local services ends up with the same problem: which container, tunnel, or leftover process owns this port, and is it something I forgot to close? Bosun answers that in one glance from the menu bar: - Every listening port (TCP), refreshed automatically, grouped by port number so multiworker services like Odoo or gunicorn collapse into one row instead of ten - Active ngrok and Cloudflare tunnels (named and quick tunnels), with the public URL one click away - VPN connection status for native macOS VPN configurations - Docker containers, showing the actual image name and Compose project instead of just "docker-proxy" - SSH -L port forwards, parsed and shown automatically - Per process CPU, memory, and uptime, on demand - One-click kill: graceful SIGTERM first, SIGKILL only if the process lingers, with group kill for multiworker services so you free the port instead of killing one worker at a time - Persistent port history with configurable retention, so you can see what was running earlier, not just right now - Global hotkey to open Bosun from anywhere Why it matters beyond convenience: a tunnel or forwarded port you forgot about is a documented way attackers keep quiet remote access once they're in. Bosun makes "what's actually exposed right now" a one-glance answer instead of something you have to go hunting for. Under the hood, Bosun is 100% native Swift and SwiftUI, no Electron, no Chromium, minimal memory and CPU footprint even with the menu bar open all day. There's no telemetry on your actual port, process, or network data, that stays local to your Mac (disclosed in full in the privacy policy at bosun.dev). Bosun requires macOS 14.0 (Sonoma) or later. It's a paid app with a 14-day free trial that starts the moment you open it, no signup or account required to try the full feature set. Pricing: Solo $12.99, Pro $21.99, and an Enterprise seat tier at $6.99/seat for teams. Built solo, and still actively maintained, if you run a lot of local containers, dev tunnels, or VPN connections day to day, I'd love your feedback.

The board it did beston sets the price. Every other board only adds to it if the launch also landed in that board's top 25% — because just showing up somewhere isn't an achievement. Listing on twelve directories is free; placing well on them isn't.
