flow

Everything you need to move your project faster

Install

Install the latest release (macOS/Linux):

curl -fsSL https://myflow.sh/install.sh | sh

Then run:

~/.flow/bin/f --version
~/.flow/bin/f doctor

If f is not found by name immediately, open a new shell (exec zsh -l on zsh).

The installer verifies SHA-256 checksums when available. If you are installing a legacy release that doesn't ship checksums.txt, it will warn and continue (GitHub download only). To bypass verification explicitly (not recommended), set FLOWINSTALLINSECURE=1.

Upgrade

Upgrade to the latest release:

f upgrade

Upgrade to the latest canary build:

f upgrade --canary

Switch back to stable:

f upgrade --stable

If you fork Flow (or publish releases under a different repo), set:

• FLOWUPGRADEREPO=owner/repo
• FLOWGITHUBTOKEN (or GITHUBTOKEN / GHTOKEN) to avoid GitHub API rate limits

If you are upgrading to a very old tag that doesn't ship checksums.txt, you can force bypassing checksum verification with FLOWUPGRADEINSECURE=1 (not recommended).

Build From Source

Clone Flow, hydrate the pinned vendor snapshot, and install an optimized local build:

git clone https://github.com/nikivdev/flow.git
cd flow
./scripts/vendor/vendor-repo.sh hydrate
FLOW_PROFILE=release ./scripts/deploy.sh
~/bin/f --version

• ./scripts/vendor/vendor-repo.sh hydrate reuses .vendor/flow-vendor if it already exists.
• If .vendor/flow-vendor is missing, it clones the pinned vendor repo from vendor.lock.toml and materializes lib/vendor/* from that exact commit.
• The pinned vendor repo is public: https://github.com/nikivdev/flow-vendor
• FLOW_PROFILE=release ./scripts/deploy.sh builds the optimized release binary and installs f / flow / lin into ~/bin (and symlinks into ~/.local/bin if that directory exists).

If you want to populate the vendor checkout yourself first, that works too:

git clone https://github.com/nikivdev/flow-vendor.git .vendor/flow-vendor
./scripts/vendor/vendor-repo.sh hydrate

Dev Fast

Typical local loop:

f setup
f test
f deploy

• f setup checks the workspace and toolchain.
• f test runs the test suite.
• f deploy builds and installs the local CLI into your path.

If you want to inspect tasks first:

f tasks list
