Your work should stay in your control.
0xPeerHold builds small, local-first developer tools that run entirely on your own machine — a command-line snippet manager and a local shared clipboard, so far. No sign-in. No server. Nothing sent anywhere. Each one is a single offline binary for Linux, macOS and Windows that keeps your data in a file you can read, back up, and take with you.
What our software will never do
- No account. We never learn your name or your email.
- No server. Nothing running that could be breached or shut down.
- No telemetry. No crash reports, no usage pings, no analytics.
- No outbound requests. Point a packet capture at it and watch nothing happen.
- No execution. Our tools move text around. You decide what runs.
- No ads, no tokens, no upsell. Free, and staying that way.
How we build Four rules. They're the reason the products look the way they do.
No servers
Our software runs locally and only locally. There is no backend to sign in to, nothing to keep patched, nothing that can be breached, and nothing that stops working when we do. Where two of your own devices need to talk — your laptop and your phone — they talk to each other directly over your network, with no relay in between and nothing switched on until you switch it on.
Your data is a plain file, or no file at all
cmdvault keeps your vault as readable JSON. Put it wherever you want — a Git repo, a Syncthing folder, an encrypted USB stick — or feed it to a language model, since it's documented JSON with no proprietary wrapper around it. pastebridge goes further and keeps nothing at all: what you paste lives in memory and is gone when the process stops.
Limitations stated up front
Limitations go in the documentation and in the app itself, in plain language, on the screen where they matter rather than behind a link.
Three, so you can see the standard. cmdvault's vault file is unencrypted plaintext and so is every export, which the About panel says out loud despite the name. Its destructive marker is a label you type by hand, so an unmarked command has not been checked and found harmless — it has not been checked at all. And pastebridge's command lane exists to be copied into a terminal, which is exactly what makes write access to it worth thinking about before you share the PIN.
Claims you can test from outside
Our software is proprietary, so you can't read the source and we're not going to imply otherwise. What we can do is make the claims that matter testable without it. Run a packet capture and watch nothing leave. Start the binary in a namespace with no network at all and watch it work identically. Fill a field marked secret with a string you'll recognize and go looking for it in the file afterwards. Each product page lists the checks we'd run in your position.
Products
cmdvault
A local command-line snippet manager: a searchable home for every command you've figured out. Write the variable parts as blanks and fill them in when you copy, instead of keeping ten near-identical entries. Keep credentials out of the file entirely, attach everything you knew about a command to the command, and carry the lot between machines as one JSON file. Switch sharing on and your phone works from the same vault.
pastebridge
A local shared clipboard, two lanes, for debugging across two machines you own on the same network. Paste terminal output on one and read it on the other; send a command back and copy it with one tap. For the Pi on the shelf, the server over SSH, and every time the error is on the screen you can't comfortably read on. It stores nothing and forgets everything when you stop it.

- Install and use on any number of devices you own, for personal or internal business use, free of charge
- Pass the binary on, provided it's unmodified, complete with its notices, and free of charge
- No modifying, no derivative works, no reverse engineering — except where your local law says otherwise and won't let that be contracted away
- Your files stay yours, readable, and unaffected if the license ends
License, Privacy, Safety notes, About, Licenses and Imprint panels are inside every app, offline, with a version and effective date on each so a support conversation can establish which text you actually saw. Published by 0xPeerHold LLC, a Wyoming limited liability company.
