Bumping deps one "go get foo@latest" at a time is slow with the ~500
modules in go.mod. This tool parses go.mod with x/mod/modfile, asks
proxy.golang.org concurrently for the newest version of each direct
dependency (about a second for the whole file), and then runs a single
"go get" with the modules that actually have something newer. Arguments
narrow it to modules whose path contains one of the given substrings,
so "bumpdeps gvisor" does the obvious thing.
gvisor.dev/gvisor, github.com/tailscale/wireguard-go, and
github.com/tailscale/golang-x-crypto follow branches ("go", "tailscale",
and "main" respectively) rather than tags, so those are resolved via the
proxy's @v/<branch>.info endpoint instead of @latest.
The --exclude-newer-than-days flag is a cooldown in the sense of
https://nesbitt.io/2026/03/04/package-managers-need-to-cool-down.html:
releases younger than that are ignored in favor of the newest one old
enough, so a compromised upstream has to go unnoticed that long before
we'd pick it up. It defaults to off. Branch-tracked modules have nothing
older to fall back to, so they're held until their head has aged.
The tool never downgrades, either by semver (the proxy's @latest can be
older than a pseudo-version we're already on) or by commit time (forks
can carry stray tags that sort above their real development branch, as
golang-x-crypto's v0.91.0 from 2024 does). It skips replaced modules and
modules whose latest release declares a different module path, since go
get rejects those and they need their import paths changed by hand.
Indirect deps are left to MVS by default; -indirect bumps them too, but
that tends to break the build when their importers haven't caught up.

Tailscale
Private WireGuard® networks made easy
Overview
This repository contains the majority of Tailscale's open source code.
Notably, it includes the tailscaled daemon and
the tailscale CLI tool. The tailscaled daemon runs on Linux, Windows,
macOS, and to varying degrees
on FreeBSD and OpenBSD. The Tailscale iOS and Android apps use this repo's
code, but this repo doesn't contain the mobile GUI code.
Other Tailscale repos of note:
- the Android app is at https://github.com/tailscale/tailscale-android
- the Synology package is at https://github.com/tailscale/tailscale-synology
- the QNAP package is at https://github.com/tailscale/tailscale-qpkg
- the Chocolatey packaging is at https://github.com/tailscale/tailscale-chocolatey
For background on which parts of Tailscale are open source and why, see https://tailscale.com/opensource/.
Using
We serve packages for a variety of distros and platforms at https://pkgs.tailscale.com.
Other clients
The macOS, iOS, and Windows clients use the code in this repository but additionally include small GUI wrappers. The GUI wrappers on non-open source platforms are themselves not open source.
Building
We always require the latest Go release, currently Go 1.27. (While we build releases with our Go fork, its use is not required.)
go install tailscale.com/cmd/tailscale{,d}
If you're packaging Tailscale for distribution, use build_dist.sh
instead, to burn commit IDs and version info into the binaries:
./build_dist.sh tailscale.com/cmd/tailscale
./build_dist.sh tailscale.com/cmd/tailscaled
If your distro has conventions that preclude the use of
build_dist.sh, please do the equivalent of what it does in your
distro's way, so that bug reports contain useful version information.
Bugs
Please file any issues about this code or the hosted service on the issue tracker.
Contributing
PRs welcome! But please file bugs. Commit messages should reference bugs.
We require Developer Certificate of
Origin
Signed-off-by lines in commits.
See commit-messages.md (or skim git log) for our commit message style.
