## Problem The dashboard's timezone picker (#45517) propagates to log timestamps and the shared TimestampInfo component, but observability and reports charts still render their X-axis labels, range labels, and tooltip headers in the browser's local timezone. The result is jarring once a user picks a non-local timezone: hover a chart and you get one tz, hover a log row and you get another. ## Fix Routes all display-side timestamp formatting in the chart layer through the existing picker-aware helpers (\`useFormatDateTime\` / \`formatDateTime\`) so chart UI matches the rest of the dashboard. - **ComposedChart.utils** \`CustomTooltip\` (the hotspot — drives every observability dashboard tooltip): reads the active timezone via \`useTimezone\` for both the header label and the formatted timestamp. - **AreaChart** / **BarChart**: introduce a \`formatChartDate\` helper that honours each component's existing \`displayDateInUtc\` prop, otherwise routes through the picker. - **ChartBlock**: the two recharts \`labelFormatter\` arrows now close over \`useFormatDateTime\`. - **ChartHighlightActions**: range labels in the zoom dropdown migrated to the same hook. Intentionally untouched (must stay UTC): - \`ChartHandler\` / \`ChartBlock\` \`startDate\`/\`endDate\` (API range params, day boundary). - \`ChartBlock.tsx:166\` explicit \`.utc()\` data-key normalisation. - \`useFillTimeseriesSorted\` and friends (range math, no display). ## How to test - Sign in. Open the avatar dropdown, pick a timezone different from your browser local (e.g. Asia/Tokyo). - Visit any project, then \`/project/<ref>/reports/database\` (or any \`/observability/...\` page). - Hover any chart series — the tooltip header should display the chosen IANA name and times in that timezone. - Click-drag a range on a chart to open the zoom dropdown — start/end labels in the menu should also be in the chosen timezone. - Switch back to "Auto detect" and confirm everything reverts to browser-local. - For an AreaChart/BarChart that uses \`displayDateInUtc\` (e.g. some legacy reports), confirm those still render in UTC regardless of picker. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Refactor** * Standardized date/time formatting across charts, tooltips, axis labels, header/footer labels, and highlight range labels in Reports and chart components. * Switched to a shared, timezone-aware formatter that respects UTC display mode or the selected picker/timezone, ensuring consistent, human-readable timestamps throughout the UI. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
Supabase Studio
A dashboard for managing your self-hosted Supabase project, and used on our hosted platform. Built with:
What's included
Studio is designed to work with existing deployments - either the local hosted, docker setup, or our CLI. It is not intended for managing the deployment and administration of projects - that's out of scope.
As such, the features exposed on Studio for existing deployments are limited to those which manage your database:
- Table & SQL editors
- Saved queries are unavailable
- Database management
- Policies, roles, extensions, replication
- API documentation
Managing Project Settings
Project settings are managed outside of the Dashboard. If you use docker compose, you should manage the settings in your docker-compose file. If you're deploying Supabase to your own cloud, you should store your secrets and env vars in a vault or secrets manager.
How to contribute?
- Branch from
masterand name your branches with the following structure{type}/{branch_name}- Type:
chore | fix | feature - The branch name is arbitrary — just make sure it summarizes the work.
- Type:
- When you send a PR to
master, it will automatically tag members of the frontend team for review. - Review the contributing checklists to help test your feature before sending a PR.
- The Dashboard is under active development. You should run
git pullfrequently to make sure you're up to date.
Developer Quickstart
Note
Supabase internal use: To develop on Studio locally with the backend services, see the instructions in the internal
infrastructurerepo.
# You'll need to be on Node v20
# in /studio
## For external contributors
pnpm install # install dependencies
pnpm run dev # start dev server
## For internal contributors
## First clone the private supabase/platform repo and follow instructions for setting up mise
mise studio # Run from supabase/platform alongside `mise infra`
## For all
pnpm run test # run tests
pnpm run test -- --watch # run tests in watch mode
Running within a self-hosted environment
Follow the self-hosting guide to get started.
cd ..
cd docker
docker compose -f docker-compose.yml -f ./dev/docker-compose.dev.yml up
Once you've got that set up, update .env in the studio folder with the corresponding values.
POSTGRES_PASSWORD=
SUPABASE_ANON_KEY=
SUPABASE_SERVICE_KEY=
Then run the following commands to install dependencies and start the dashboard.
npm install
npm run dev
If you would like to configure different defaults for "Default Organization" and "Default Project", you will need to update the .env in the studio folder with the corresponding values.
DEFAULT_ORGANIZATION_NAME=
DEFAULT_PROJECT_NAME=
