Flagsmith CLI

The next-generation Flagsmith command-line interface (work in progress).

Install

curl -fsSL https://raw.githubusercontent.com/Flagsmith/flagsmith-cli/main/install.sh | sh

Installs to $HOME/.local/bin and adds it to your PATH. Options:

curl -fsSL https://raw.githubusercontent.com/Flagsmith/flagsmith-cli/main/install.sh | sh -s -- --version v2.0.0 --bin-dir /usr/local/bin --no-modify-path
curl -fsSL https://raw.githubusercontent.com/Flagsmith/flagsmith-cli/main/install.sh | sh -s -- --help

FLAGSMITH_CLI_VERSION, FLAGSMITH_INSTALL_DIR and FLAGSMITH_NO_MODIFY_PATH do the same if exported first.

To pin the installer itself, fetch it at a commit you trust: raw.githubusercontent.com/Flagsmith/flagsmith-cli/<sha>/install.sh.

Alternatively, go install github.com/Flagsmith/flagsmith-cli/v2@v2.0.0-beta.2 (installs as flagsmith-cli), or grab an archive from Releases.

On Windows:

irm https://raw.githubusercontent.com/Flagsmith/flagsmith-cli/main/install.ps1 | iex

Build

go build -o flagsmith .

Docker

docker run --rm -v "$PWD:/work" -e FLAGSMITH_API_KEY ghcr.io/flagsmith/flagsmith-cli flag list

A container has no keyring, so flagsmith login cannot store credentials there — pass FLAGSMITH_API_KEY or FLAGSMITH_ENVIRONMENT_KEY.

Quickstart

flagsmith init          # log in, pick a project + environment, write flagsmith.json
flagsmith flag list    # list the flags in the current environment

Commands

• flagsmith init — bind the current directory to a project (writes flagsmith.json).
• flagsmith flag list — list feature flags in the current environment.
• flagsmith flag get <feature> — show a single flag's state (--segment <id> or --identifier <id> for an override).
• flagsmith flag update <feature> — toggle (--enable/--disable) or set the value (--value, --type); --segment <id> or --identifier <id> targets an override.
• flagsmith flag enable|disable <feature> — shorthand for flag update --enable/--disable (same --segment/--identifier targeting).
• flagsmith flag delete <feature> --segment <id>|--identifier <id> — delete a segment or identity override.
• flagsmith segment list — list segments (--include-feature-specific to include feature-scoped ones).
• flagsmith segment get <segment> — show a segment and its rule tree.
• flagsmith segment create <name> --rules @rule.json — create a segment (--description, --feature).
• flagsmith segment update <segment> — replace the rules (--rules), description, or feature.
• flagsmith segment delete <segment> — delete a segment.
• flagsmith feature list — list project features (--include-archived).
• flagsmith feature get <feature> — show a feature and its variants.
• flagsmith feature create <name> — create a feature (--value, --enabled, --description, --variants).
• flagsmith feature update <feature> — update description or archive (--description, --archive/--unarchive).
• flagsmith feature delete <feature> — delete a feature.
• flagsmith feature variant list|add|update|delete <feature> — manage a multivariate feature's variants (by id or key).
• flagsmith organisation list|get|create|update|delete (alias org) — manage organisations.
• flagsmith project list|get|create|update|delete — manage projects (create uses --organisation).
• flagsmith environment list|get|create|update|delete|clone (alias env) — manage environments (by name or API key).
• flagsmith environment key list|create|delete <environment> — manage server-side SDK keys.
• flagsmith environment document [environment] — output the environment document (local-evaluation JSON).
• flagsmith evaluate [feature] (alias eval) — the flags an SDK resolves for the current environment (--identity, --trait key=value, --persist); --js writes the state a frontend SDK hydrates from, --test fails when a named flag is disabled.
• flagsmith config — show the resolved context and where each value comes from.
• flagsmith login / logout — browser OAuth (PKCE, loopback); also auth login/auth logout.
• flagsmith auth status — identity, organisations, credential source, token expiry.
• flagsmith auth token — print the active Admin API credential for curl/scripts.
• flagsmith api <path> — call any Flagsmith endpoint with the CLI's credentials applied (curl-like; --sdk for the SDK API, -F/-f fields).

Conventions

• --json (or FLAGSMITH_JSON_OUTPUT) for machine-readable output; --jq <expr> to filter it.
• Static credentials: FLAGSMITH_API_KEY (Admin API), FLAGSMITH_ENVIRONMENT_KEY (SDK).
• Self-hosted: --api-url or FLAGSMITH_API_URL.
