Download VeloUtils

Version 1.0.0 for macOS, as a disk image signed with a Developer ID and notarized by Apple. Free, with no account.

Disk image, 4.6 MB · macOS 26.0 or later · Apple silicon and Intel

Requirements

macOS	26.0 (Tahoe) or later
Mac	Apple silicon or Intel — one universal app runs on both

Install

Open VeloUtils-1.0.0.dmg from your Downloads folder.
Drag VeloUtils onto the Applications folder beside it.
Open VeloUtils from Applications. The first time, macOS asks whether you want to open an app downloaded from the Internet. Click Open.

That question is the only one you should see. VeloUtils is notarized by Apple, and the notarization ticket is stapled to both the app and the disk image, so macOS can confirm it without a network connection. If macOS shows any other warning — that the app is damaged, or that Apple could not check it — do not open it. Check the SHA-256 below, and write to support@veloutils.app.

To confirm your copy is byte for byte the one published here, open Terminal in the folder that holds it — usually cd ~/Downloads — and run:

shasum -a 256 VeloUtils-1.0.0.dmg

The 64 characters it prints must match the SHA-256 above exactly. If they differ, do not open the file.

To ask Gatekeeper about it directly:

spctl -a -t open --context context:primary-signature -v VeloUtils-1.0.0.dmg

It reports accepted and source=Notarized Developer ID.

Release notes

1.0.0

The first release: four tools in one native window, and all four work offline.

Markdown — a split editor and live preview with synchronized scrolling, and find in both panes.
JSON — format or minify without touching your input. It validates as you type, sorts keys, and numbers keep every digit.
CSV and TSV — automatic delimiter detection, search, per-column filters, and a multi-column sort that orders numbers as numbers. Copy the visible rows, or just the selected ones, as JSON or as a Markdown table.
Mermaid — a live diagram that keeps the last good render on screen while you fix an error. Templates, zoom and pan, and export to PNG and SVG.

No account, no ads, no analytics and no telemetry. The only network request the app makes is for a remote image that a Markdown document itself links to.

Help › Send Feedback… and the envelope in the sidebar footer open a pre-filled email draft in your mail app. Nothing is sent until you send it.

This direct-download version adds a Buy Me a Coffee strip to the sidebar. It also shows a reminder, but only once you have opened the app on 14 different days, then at most once every 30 days, and never again after you choose Don't show again. Both open buymeacoffee.com in your browser. The Mac App Store version, in preparation, has neither.

VeloUtils 1.0 reads files but does not save edits back to them. That and the other known limits are on the support page.

The privacy policy was revised for this release, effective 27 September 2026, to describe the strip, the reminder, the three values the reminder stores on your Mac, and the links that open in your browser or mail app. It also now says that deleting the app leaves its stored values behind, because macOS keeps the app's container.
