FLUXTAB

SEE THE BILLBEFORE ITHITS.

One live ledger for OpenAI, Anthropic, and OpenRouter — with staged alerts in chat and an AI spend budget gate (a budget trajectory check, not PR cost prediction).

Security / architecture

Not in yourrequest path.

Fluxtab reads billing APIs. Production traffic still goes straight to OpenAI, Anthropic, and OpenRouter.

Read-only keys · Vault-encrypted · Separate CI token

01
Read-only keys
Usage and billing scope only. Fluxtab never sits in your request path, never sees prompts, and cannot spend on your providers.
02
Vault-encrypted
Keys are encrypted in Supabase Vault the moment they arrive, decrypted only in memory during a sync, never sent to the browser.
03
Separate CI token
Pipeline tokens can read spend numbers. They cannot read provider keys. Revoke either independently from Settings.

What you get

See. Explain.Control. Integrate.

Four moves, one story — from the ledger to the workflow, not a flat feature dump.

01See
The bill, in one ledger.
OpenAI, Anthropic, and OpenRouter on one timeline — with a month-end pace so you know where the cycle is heading.
- Normalized daily spend
- Forecast from last 7 days
- All three providers
02Explain
Why it moved.
Project splits, a spend heatmap, and same-day spike detection — so a jump is a cause, not a mystery.
- Per-project attribution
- Anomaly detection
- Daily spend heatmap
03Control
A budget with brakes.
One monthly threshold. Staged alerts at 50 · 80 · 100 · 120%. The AI spend budget gate fails the deploy when the account is already over.

04Integrate
Where the team already works.
Read-only API, webhooks, Slack / Discord / Teams, and shared team seats — no SDK in your request path.

SETUP

KEYS IN.SIGNAL OUT.

Three moves from scattered billing portals to a live cost signal your team — and your pipeline — can act on.

01
Connect providers
Paste OpenAI, Anthropic, or OpenRouter admin keys. Encrypted in Vault — no SDK, no proxy.
02
Watch the ledger
Daily sync into one timeline, with forecast, heatmap, and project splits as data lands.
03
Alert & automate
Staged alerts in chat. CI runs a budget trajectory check before deploy.

04 / FIELD NOTES

BEFORE YOUCONNECT A KEY.

The useful answers, without a sales call or a forty-page security deck — including what Fluxtab can and can't stop.

01Does Fluxtab sit in front of my API traffic?

No. Fluxtab reads billing and usage data from provider APIs. Your production requests keep going directly to OpenAI, Anthropic, OpenRouter, or whichever provider you use.

02What happens on the free tier?

You can connect one provider, view 7 days of history, and get a Slack alert when you cross your monthly threshold. It is enough to see whether the workflow fits before upgrading.

03How do alerts work?

You set one monthly threshold. On Free you get a single alert at 100%. On Pro and above, Fluxtab warns you in stages — 50%, 80%, 100%, and 120% — and separately flags any day where spend spikes well above your recent average. Alerts deliver to Slack, Discord, Microsoft Teams, email, or a raw webhook, depending on plan.

04What are the slash commands?

Type /fluxtab spend in Slack or Discord and the bot replies with month-to-date, forecast, and per-provider spend — private to you, no dashboard tab needed. Available on Pro and above.

05How does the AI spend budget gate work?

Your pipeline calls a single endpoint with a read-only bearer token. This checks your account's budget trajectory as of this PR — it does not yet calculate the specific cost impact of the code change itself. If you're already over budget it returns a failure your CI treats as a failed step. Available on Business and Team plans, along with the public summary API.

06How do team seats work?

On the Team plan you can invite up to 5 teammates to the same cost ledger with their own logins. Everyone sees the same numbers; nobody shares provider keys over chat.

07Does history length apply equally to all providers?

OpenAI and Anthropic history follows your plan's range (7/30/90/full days). OpenRouter is capped at the last 30 days regardless of plan, due to a limitation in OpenRouter's own usage API — we'll lift this if OpenRouter's longer-range analytics endpoint becomes stable.

08Where are provider keys stored?

Keys are handled server-side and stored through the app's Supabase-backed secret workflow. They are not exposed to the browser, and public API tokens can never read them.

09Can Fluxtab stop spend before it happens?

Not at the provider level. Connected keys are read-only by design — that's what makes them safe to hand over — so Fluxtab alerts you rather than blocking a request. The one place it can hard-stop something is your own pipeline: the AI spend budget gate fails the build when the account is already over budget.

10Does my provider's own budget limit stop spend?

Not reliably. As of 2026, OpenAI's account budget setting notifies but doesn't hard-stop requests, and Anthropic has no equivalent cap for standard API keys. Treat Fluxtab and your provider's own settings as early warning, not a guarantee.

11What is the forecast based on?

Your last 7 days of usage, projected to the end of the billing cycle. It's an estimate, not a guarantee — shown only once you have at least 3 days of data.

12How often does data refresh?

On Free, provider usage syncs about every 6 hours. On paid plans, sync runs every hour. This isn't live monitoring — a spike shows up same-day, not same-minute. You can always tap Sync now on the dashboard.
