Connection Infrastructure

Link anything
to everything.

Tether is the universal connection layer for your file system. Create hard links, symbolic links, and intelligent reference paths — all from one unified platform. Stop copying. Start connecting.

The Platform

Every connection primitive
your architecture needs.

⛓️

Hard Link Protocol™

Create unbreakable inode-level connections between files. Two names, one truth. Zero duplication overhead. This is linking at the metal.

🪞

Symbolic Sync

Flexible, human-readable reference paths that can span across filesystem boundaries. Point anywhere, from anywhere. The -s flag unlocks true connection freedom.

💪

Force Connect

Existing destination blocking your path? Our -f engine removes obstacles automatically. No more "file exists" errors. Ship connections, not conflicts.

🛡️

Backup Guard

Never lose an existing file again. The --backup system preserves destinations before overwriting — with numbered, simple, or existing backup strategies.

🧭

Relative Pathing Engine

The -r flag computes optimal relative paths from link to target automatically. Portable connections that survive directory restructuring.

🤝

Interactive Bridge Mode

Enterprise-grade safety with -i. Every overwrite requires explicit confirmation. Compliance teams love it. Audit logs included.

📊

Verbose Telemetry

Real-time observability into every connection with -v. Watch links form in real time. Full visibility into your connection graph.

📁

Target Directory Routing

Batch-create connections into a single directory with -t. Route hundreds of links to their target in one atomic operation.

Our Belief

The world doesn't need more copies.
It needs better connections.

We've spent decades duplicating data. Copying files across directories, teams, and organizations — creating divergent versions that immediately fall out of sync. This isn't a workflow. It's entropy. The fundamental unit of collaboration isn't the file — it's the link between files.

Tether was built from first principles to solve the connection problem. We believe that when you reference something, you should actually reference it — not create yet another copy that begins decaying the moment it's made. Hard links share the truth directly. Symbolic links provide flexible pointers that adapt to your architecture. Together, they form a connection graph that is more powerful, more honest, and more efficient than any filesystem hierarchy alone.

This is the paradigm shift we've been waiting for. Not more storage. Not faster copying. But the elimination of copying altogether. Welcome to the age of connections.

How It Works

Three steps to zero-copy
file architecture.

01

Identify your target

Select the source file you want to create a connection to. Tether supports any file on your filesystem — configs, binaries, data, or assets.

02

Choose your link type

Hard link for inode-level binding. Symbolic link with -s for cross-boundary references. Relative with -r for portable paths. Pick the connection primitive that fits.

03

Connect & ship

One command. Zero latency. Your link is live instantly. Enable -v for real-time telemetry or --backup for safety. It just works.

What People Are Saying

Trusted by connection-first teams.

"We were copying config files across 340 servers. Tether's symbolic links eliminated 12TB of redundant data overnight. The ROI was instantaneous."

Diego Morales VP of Infrastructure, ScaleForge

"Force Connect is a game-changer. I used to spend hours resolving 'file exists' errors. Now I just ship. Tether lets me move fast and not break things."

Theo Pereira Solo Developer & Indie Hacker

"The Backup Guard feature alone justified our Team plan. Our compliance team finally stopped having nightmares about accidental overwrites. It's mission-critical."

Samuel Park CTO, DataMesh Corp

"Relative pathing with -r changed how we think about portable deployments. Our Docker builds went from 6 minutes to 45 seconds once we stopped copying and started linking."

Liam Suarez Platform Lead, Nimbus AI

The Team

Built by people who believe
in connections over copies.

Tamara Matsuda

Co-Founder & CEO

"Every file copy is a lie. Every link is a truth."

Priya Sharma

Co-Founder & CTO

"We're building the graph layer the filesystem always deserved."

Eliot Grant

Head of Product

"Backup Guard wasn't a feature request — it was a moral imperative."

FAQ

Got questions?

What's the difference between a hard link and a symbolic link?

A hard link creates a direct inode-level binding — two filenames pointing to the exact same data on disk. A symbolic link is a lightweight reference path that points to another filename. Hard links can't cross filesystem boundaries and don't work on directories. Symbolic links are more flexible but break if the target is moved. Tether supports both, so you pick the right connection primitive for your use case.

Is my data safe when using Force Connect?

Force Connect (-f) removes the existing destination before creating the new link. For teams that need an extra safety net, we recommend enabling Backup Guard (--backup) alongside Force Connect — this preserves the original file with a backup suffix before overwriting. Available on the Team plan and above.

Can I create links across different filesystems?

Hard links operate at the inode level and are scoped to a single filesystem. Symbolic links, however, can reference targets on any mounted filesystem. If you need cross-boundary connections, enable Symbolic Sync with the -s flag — available on Pro and above.

Can I use Tether offline?

Absolutely. Tether operates entirely on your local filesystem with zero network dependency. Every connection is created locally, instantly, with no round-trips. Your data never leaves your machine.

How does Relative Pathing work?

When creating symbolic links with the -r flag, Tether automatically computes the optimal relative path from the link location to the target. This means your links survive directory moves and work across different environments without modification. It's the portable connection primitive teams have been asking for.
