The fadebox CLI
fadebox is a single native binary that drives the same API the UI does, authenticating with an
API key. It was built for pipelines — the useful half is not wrapping REST calls,
it is the deploy loop, since deploy is asynchronous and anything that gates a build on an
environment coming up has to poll, decide what counts as success, and report why it failed.
It works just as well from your own machine. Any key drives it, so you can point it at a key of your own and act as yourself, or at a service account's key and act as the pipeline does. If you sign in through SSO you have no password, so a personal key is how you use the CLI at all.
If what you want is an agent driving Fadebox rather than a command you type, that is the MCP endpoint instead.
Install
Every Fadebox server hands out the CLI it was released with, so the download is your own installation, not a release page:
curl -fsSL -o fadebox https://fadebox.example.com/cli/fadebox-linux-amd64
chmod +x fadebox
sudo mv fadebox /usr/local/bin/fadebox
The download needs no sign-in — a pipeline's first step has nothing but the server's address, and
that is enough — and it is always the server's own version: after an upgrade,
download it again and fadebox --version matches the version in the sidebar footer. That footer
links it too, as CLI beside the version, on every page. The binary's third-party notices sit
beside it at /cli/fadebox-cli-THIRD-PARTY-NOTICES.txt, and the License page lists them with the
server's own.
It is a native binary for Linux on amd64 with no runtime dependency — nothing to install alongside it. A development build of Fadebox carries no CLI and says so at that URL; a released image always does.
Connect
login verifies a key against a server and stores it as a context:
fadebox login --url https://fadebox.example.com --project demo --env dev
It prompts for the key so it does not land in your shell history, calls /api/me to confirm it
works, and writes ~/.config/fadebox/config.yaml — created with mode 0600 before anything is
written to it, so the token never touches disk world-readable.
Whatever login prints back is who the CLI now acts as: your own username for a personal key, the
service account's for a CI one. Every command afterwards reaches exactly as far as that account
does.
Contexts are named, so one machine can talk to several installations:
fadebox context list
fadebox context use staging
fadebox context current
In CI, write no file at all. Every setting resolves flag → environment variable → context file:
| Flag | Environment variable |
|---|---|
--url | FADEBOX_URL |
--token | FADEBOX_TOKEN |
-p, --project | FADEBOX_PROJECT |
-e, --env | FADEBOX_ENV |
FADEBOX_CONFIG_DIR relocates the context file if you do want one.
The deploy loop
fadebox instance up pr-123 --wait --timeout 10m
upis find-or-create. If an instance with that slug exists it is reused and redeployed; otherwise it is created first.instance createstays strict by comparison — the API disambiguates a repeated name intopr-123-2rather than failing, which is right for a UI and a quiet duplicate-per-retry for a pipeline.--waitpolls status and renders per-container state and health as they come up. It exits0onRUNNINGand1onERROR, printing the failure reason the UI would show — otherwise only reachable by having a human open the UI.RUNNINGis as strong as the template's healthchecks: a service that declares one counts as ready when it turns healthy, one without the moment it starts — so on a healthcheck-less stack--waitcan return before the app accepts a connection.--timeout(default10m) and--poll-interval(default2s) bound the wait. They accept90s,10mand the like.- On success it prints the instance's URLs, taken from the deployed containers.
--runtimeapplies on create only — an existing instance keeps its runtime untilinstance movechanges it, which needs the instanceDRAFTorSTOPPED. Left out, the server pickslocalwhen it is enabled and available to the project, otherwise the project's only enabled runtime, and answers409 runtime_unavailablewith the candidates when several qualify — name one then.instance listandgetmark a runtime that has since been disabled as(disabled): the instance cannot deploy there, see Runtime.- Deploying re-arms the instance's lifetime. A branch that keeps getting pushed keeps its
environment alive; one that goes quiet is stopped once the
expiry runs out, and
instance getprints when that is. instance listhas aHEALTHcolumn besideSTATUS, andinstance getprints aHealthline, carrying what the daemon last said — status is what fadebox did, health is what is running now. A pipeline can gate on it:RUNNINGmeans the deploy finished,HEALTHYmeans it is still up.--purposeand--linksay what the copy is for — the branch, the merge request, the ticket — so the instance list reads as something other than a wall of slugs. Both work oncreateandup,--linkis repeatable, and they stick to the instance across every redeploy.instance listshows the purpose in aPURPOSEcolumn, cut at 40 characters.--sharedand--personalsay whose the copy is: every deployer's, or the creator's and the editors' alone. Both work oncreateandup, on create only — an existing instance keeps its sharing, andupsays so when the flag disagrees — and left out, the environment's own default applies.instance shareandinstance unsharechange it afterwards, which is the creator's or an editor's to do.instance listshows it in aSHARINGcolumn andinstance getprintsShared: no (personal to alice); astopordeletethe account may not make prints the server's refusal, which names whom to ask.--print-tokenmints the ingress cookie for an instance on a runtime that requires a sign-in, so the suite can open the URL the deploy just printed. It implies--waitand adds anaccessTokenkey to the status document; against an ungated runtime the key is there with an empty token list, so the step needs no condition around it.
What an instance runs is its environment's definition, read fresh on every deploy — an instance
carries no parameters of its own. To deploy other versions, set them on the environment first
(env service set), or clone the environment into a second
version stream (env clone).
A blueprint environment refuses instances altogether —
instance create and up answer 409. env list marks one in its KIND column and env get
prints a Blueprint: line, so a pipeline that must not assume can check before it deploys. Cloning
a blueprint yields a deployable environment, so env clone base dev then instance up is the way
through.
--wait is available on up, deploy and stop.
Command surface
fadebox login | Verify a key and store a context. |
fadebox context list | use | current | Switch between installations. |
fadebox env list | get | Environments of the project. |
fadebox env clone <source> <slug> | Copy an environment's definition — the second version stream, and how a blueprint is used. |
fadebox env service set <name> --image-tag … | Set what a service runs: image tag, env overrides, job flag. A full replace — options left out are cleared (except --job). |
fadebox instance list | get | create | up | deploy | stop | delete | The instance lifecycle. |
fadebox instance move <slug> --runtime <runtime> | Move a DRAFT or STOPPED instance to another runtime. Its volumes do not follow and the new runtime has its own ingress domain, so the next deploy comes up on new URLs and empty — see Runtime. |
fadebox instance reset <slug> --yes | Wipe the instance's data — containers, network and volumes — and deploy it again with the same overrides. --yes is required when stdin is not a terminal. |
fadebox instance set <slug> --var … --tag … [--redeploy] | Set this instance's values on the environment's open services. A full replace: send every override it should end up with, or --clear to remove them all. |
fadebox instance describe <slug> --purpose … --link … | Say what this copy is for: one line and up to eight labelled links. Pass only one of the two and the other is carried over; --clear removes both. |
fadebox instance share | unshare <slug> | Make an instance every deployer's, or its creator's alone — see Ownership. The creator's or an editor's to do. |
fadebox instance check <slug> <name> --state passed|failed|pending | Report a named check on what the instance is running now — --summary for the line, --run-url for the job, --remove to delete it. |
fadebox instance approve | reject <slug> --note … | A person's verdict on what is running. A rejection must carry the note. |
fadebox instance verdict <slug> [--withdraw] | Print the verdict that stands, or take it back. |
fadebox instance token <slug> | Mint the ingress cookie for an instance behind Require fadebox sign-in — one value per hostname, valid 12 hours. An ungated runtime answers with none. |
fadebox instance status | logs | Live state and a log snapshot — for a stopped instance, the log captured at the stop, with a note on stderr. |
fadebox template list | get | Templates visible to the key's account. |
fadebox runtime list | Runtimes; narrowed to those the project may deploy onto. CPU and MEMORY show what each host is spending against its capacity, as of the last reading — – where nothing has been observed yet. |
create and up take the same --var <service>:<KEY>=<value> and --tag <service>=<tag> flags,
both repeatable, so an instance can be made with its values in one call:
fadebox instance up pr-1842 --tag backend=2.7.0-rc3 --var backend:LOGGING_LEVEL_ROOT=DEBUG --wait
Whether a service accepts either is the server's decision, so a closed one fails fast with the
400 it would give anyone. Setting values does not deploy — add --redeploy to set to follow
through.
Every command reaches exactly as far as the key's account does — a 403 means a missing role,
exactly as it would for a person.
A 401 means the server would not accept the token at all. The CLI cannot tell you which reason,
because the server deliberately gives the same answer to every one of them — a wrong secret, a key
that was revoked or has expired, a deactivated account, and an account being made to change its
password all come back identically, so the endpoint cannot be used to probe which keys exist. The
things worth checking, in the order they usually bite: has the key expired (its expiry is on the
key's row in the UI), was it revoked, and can the account still sign in at all.
Output and exit codes
-o table (default), -o json and -o yaml. Every command emits one document, so jq reaches
any single field of a result. A table renders timestamps in your shell's own time zone; json
and yaml carry them as the API does, as instants with the offset spelled out
(2026-08-16T09:30:00Z). A status document keys its containers by service, so one service
is an address rather than a search:
fadebox instance status pr-123 -o json | jq -r '.containers.web.urls[0]' # one service's URL
fadebox instance status pr-123 -o json | jq -r '.containers[].urls[]' # every URL
fadebox instance status pr-123 -o json | jq -r '.containers | keys_unsorted[]' # the services
A service has one URL per ingress port, so urls is a list even for a single service. Beside
containers, a status document carries checks (keyed by check name), verdict and
references — the facts the card shows about
what is running — so a job can read back what it reported without a second call. instance get
prints the same as Purpose:, Links:, Checks:, References: and Verdict: lines.
--wait writes its live container progress to stderr, and only the final result to stdout. So
URL=$(fadebox instance up pr-123 --wait -o json | jq -r '.containers.web.urls[0]') captures the
URL alone while you still watch the deploy happen in the job log.
| Exit code | Meaning |
|---|---|
0 | Success. |
1 | The operation failed — a deploy that ended in ERROR, or any 4xx/5xx. |
2 | Usage error. |
Conflicts arrive as plain text and are printed as such: "Instance is RUNNING — stop it before deleting" is the message, not the status line.

fadebox instance check "$I" e2e --state passed \
--summary "84 passed, 0 failed" --run-url "$CI_JOB_URL"
If the deploy fails, instance up --wait exits 1 with the reason and the pipeline stops there.
Report --state failed from the job's failure path and the instance carries the bad news on its
own card, where whoever opens the merge request will look.
The teardown — fadebox instance stop "$I" --wait then fadebox instance delete "$I" — belongs
on the merge or close event rather than at the end of this job. The
purpose, the check and the verdict are only
worth recording on a preview somebody can still open; a stop three seconds after the suite passes
leaves nothing to review. What keeps that from accumulating copies is the
expiry, not the pipeline.
Note that the image tags land on the environment, so every instance of dev follows them —
right for one version stream per environment. Streams that must not share versions are separate
environments (fadebox env clone dev dev-v2, target with FADEBOX_ENV). Editing an environment
is a maintainer act, so a pipeline that pins versions needs its key issued
with that role — or no write access at all: with a git value source as
the tag, the env service set calls disappear entirely, the deploy reads the version from your
values file, and the default deployer key suffices.
Not yet
logsis a snapshot, not a stream.-fwould mean polling and de-duplicating a tail window, which is wrong at the edges; it waits for a streaming endpoint rather than being faked.- No
apply. Pushing a directory of template and environment manifests into an installation is designed but unbuilt; today the CLI drives instances and edits environments — it does not create templates or environments from scratch. - Linux amd64 only as a published binary.
