High Dashboards system

Cost & Usage View

A cost-awareness dashboard that pulls usage and spend signals from the actual infrastructure — Supabase (DB size, egress, compute, MAU), Vercel (bandwidth, function/edge usage, build minutes), and any metered API/email usage — into one view with trend and budget thresholds, so surprise bills are caught before the invoice. It reads provider usage APIs/billing exports on a schedule and trends them. Pure observability over cost; it does not change infrastructure or plans.

System facts

Cost & Usage View uses a reporting model and review layer for Dashboards. A cost-awareness dashboard that pulls usage and spend signals from the actual infrastructure — Supabase (DB size, egress, compute, MAU), Vercel (ba... The architecture connects identify the available usage, vercel api, supabase usage + postgres, and owner review with an explicit control path.

Outcome

Owners see infrastructure cost as a tracked trend with early warnings — no more surprise overage bills, and a clear view of which resource (DB egress, Vercel bandwidth, email) is driving spend.

Main risk

Provider usage APIs/exports change, rate-limit, or report with lag, so the numbers are incomplete or out of date and a spike is missed.

Prevention

Snapshot daily into your own table (decoupled from live API availability), show data-as-of timestamps, and fail soft so one provider's outage doesn't blank the whole view.

Fallback

If a provider lacks a usable usage API, fall back to a manually imported monthly billing CSV for that resource and keep automated snapshots for the providers that support them.

    Build a scheduled fetch (Vercel Cron or Supabase Cron + edge function) that records daily usage snapshots into a usage table so trends and month-to-date projections are computable.

  3. 03Vercel API

    Vercel API (usage/billing) contributes the trusted model for Cost & Usage View so metrics are defined before they are visualized.

  4. 04Supabase usage + Postgres

    Render a cost/usage panel (server component) with current month-to-date, trend per resource, and a simple projected-end-of-month figure against a configured budget.

How it is built

Build steps

A cost-awareness dashboard that pulls usage and spend signals from the actual infrastructure — Supabase (DB size, egress, compute, MAU), Vercel (bandwidth, function/edge usage, build minutes), and any metered API/email usage — into one view with trend and budget thresholds, so surprise bills are caught before the invoice. It reads provider usage APIs/billing exports on a schedule and trends them. Pure observability over cost; it does not change infrastructure or plans.

  1. 01Identify the available usage signals and how to fetch them: Supabase project usage (DB size/egress/compute via dashboard/API), Vercel usage (bandwidth/functions/builds via the Vercel API), plus metered email/API counts.
  2. 02Build a scheduled fetch (Vercel Cron or Supabase Cron + edge function) that records daily usage snapshots into a usage table so trends and month-to-date projections are computable.
  3. 03Render a cost/usage panel (server component) with current month-to-date, trend per resource, and a simple projected-end-of-month figure against a configured budget.
  4. 04Add threshold alerts (resource > X% of plan/budget, or sharp day-over-day spike) routed to the existing report/email path so cost creep is flagged early.
