NocoDB Supabase Airtable Grafana Metabase GitLab Excalidraw On-device AI + Add yours

One native iPhone app for the self-hosted tools teams already run. Install it, point it at your data, and your whole team gets the same app. It talks straight to each tool's API: no fork of the tool, no server of ours, no migration. The AI runs on the phone.

The gap

Enterprise open source still lives in a desktop browser

These tools won on self-hosting, price and control. The people who depend on them aren't always at a desk, though: the caterer at a venue walkthrough, the on-call engineer at dinner, the lead approving a merge between meetings. The web UIs technically load on a phone. Nobody wants to use them there.

Day one

Install it, and it works with the data you already have

The hard problem isn't the charts. It's the first five minutes: getting a team's real data onto everyone's phone without an IT project. OpenDesk handles that inside the app.

ConnectYour NocoDB, or your Supabase appPaste a URL and a token, or sign in as a user of your own Supabase app.

ImportAirtable or a spreadsheetPaste an Airtable base link and NocoDB's own importer copies every table. Or pick a CSV from Files and the column types are detected for you.

TeamAdmins set it up onceCreate a team, publish the connections, and share a 6-letter code or QR. Members sign in and get the same app.

WorkEvery tab fills inBoards, charts, alerts and AI, on your real data, with your permissions.

What's built

Six tools, one app, all on live data

Events table as a Kanban board grouped by stage, with a dollar total per lane

Review changes sheet: Summit Bank Holiday Party, Stage Tasting to Booked, Lead Captain to Dana

Tables · NocoDB

A CRM in your pocket, modeled on a real catering business

Any base: a list, a drag-and-drop board on any select field, and auto-built charts.
A typed editor with select chips, dates, star ratings, and tap-to-call or tap-to-email.
Tell it what changed. Hold the mic and say "Summit Bank tasting went great, book it, Dana captains." You get a diff to review, and tapping Apply writes it back.
Works offline from the last sync, and says so.

A Supabase table, Catering Inquiries, shown as a board grouped by its Postgres enum stages

Insights: 38 rows, $246K total budget, budget by stage chart

Tables · your Supabase app

Your Supabase app's data, with your security rules

Sign in as a user of your own app, not an admin. The phone never holds a service key.
Every read and write carries that user's token, so row-level security decides what each teammate sees. The demo table is scoped per team.
Postgres types map to the same UI: enums become board lanes, and money, dates and emails get proper editors.
Setup is one read-only SQL helper that lists the tables the signed-in user can already read.

Grafana Cart Service dashboard redrawn as native line charts

Alerts inbox: 23 firing, 1 pending, critical first, with a Triage button

Dashboards · Grafana

Charts redrawn natively, plus an on-call inbox

Each panel's query is replayed through Grafana's datasource API and drawn with Swift Charts you can scrub. Anything it can't replay falls back to a server-rendered image.
Alerts shows what's firing, critical first. Triage asks the AI what on-call should look at first.

Metabase E-commerce dashboard: stacked revenue by category, orders by category lines

GitLab merge request with an AI brief: what it does, risk, what to check

Analytics · Metabase · Code · GitLab

BI you can read on a phone, and code review between meetings

Metabase dashboards and tabs, with every question redrawn natively: KPIs with trend, lines, stacked bars, pie, funnel, scatter and tables.
GitLab merge requests, issues, pipelines and diffs, plus a 30-run CI health strip. Summarize this change tells you what it does, how risky it is, and what to check.

Excalidraw board generated from NocoDB: an events pipeline wall with sticky notes per stage

Whiteboard · Excalidraw

Your data, drawn

Map my database turns every NocoDB base and table into a hand-drawn entity map.
Pipeline wall turns your deals into sticky notes, one lane per stage, ready for a planning meeting.
Full open-source Excalidraw for editing. Boards save on the phone and export as standard .excalidraw files.
Also on the phone: a home and lock screen widget, and Siri ("What's booked next in OpenDesk?").

Teams

Admins set it up once. Everyone gets the same app.

Admin

Creates the team and connects the tools
Publishes the connections to the team
Invites by 6-letter code, link or QR
Promotes, demotes and removes members. The last admin can't be removed.

Member

Signs in with an email link or password
Joins with the code, and every tab fills in on launch
Sees Supabase rows their account is allowed to see
Can leave the team at any time

Under the hood

Supabase Auth, Postgres, and row-level security on every table
Members can read the shared setup but not change it; strangers see nothing (tested)
Sessions stored in the iOS Keychain

The on-device model is small, so it gets three constraints: the app narrows the table to the few rows an instruction plausibly names, passes each select column's allowed values, and lists the existing names for short-vocabulary columns. A person reviews every write.

Why a phone app

Things a browser tab can't do

The web UIs of these tools already exist. What was missing is everything that only works when the app lives on your phone.

Built

Siri: "What's booked next in OpenDesk?"
Voice edits: hold the mic, say what changed, review, apply
Widgets: pipeline value and next events on the home and lock screen
Live notifications: a teammate moves a deal and your phone buzzes
Offline: keeps working at a venue with no signal
On-device AI: answers without your data leaving the phone

Live Activities: an event-day countdown in the Dynamic Island
Interactive widgets: "Mark booked" or "Silence alert" without opening the app
Push when the app is closed: Supabase Edge Functions through Apple's push service
Shortcuts automations: arrive at a venue and today's event opens

Later

Camera: scan a business card into your CRM, photograph setups onto an event
Maps: travel time to load-in
Face ID: lock client data
Calendar and Apple Watch: booked events in your calendar, alerts on your wrist

Extend it

Your tool isn't here? Fork it and ask your coding agent.

OpenDesk is open source, and every tool is the same small pattern: a REST client plus a couple of screens. The repo ships an AGENTS.md that teaches a coding agent that pattern, so adding Twenty, Plane, Zammad, Baserow or your in-house tool is a conversation, not a project.

1Fork the repogithub.com/jackmielke/opendesk

2Tell your agent what you useClaude Code, Cursor, anything that reads the repo.

3Build and installIt adds the client, screens, settings, a Home tile, team sync and AI context, then checks them in the simulator.

You, to your coding agent Add an OpenDesk connector for Twenty CRM at https://crm.mycompany.com. Follow AGENTS.md.

For table-shaped data it's even shorter: implement one TableSource, and the list, board, charts, editor and voice edits all come for free. That's how the Supabase connector was built.
