--- title: "Core Nano: a complete app platform for €25 a month" description: Database, accounts, storage and hosting on one box in the Netherlands. 30 days free, then €25 a month, fixed. Your building joins the same flows as your orders. url: "https://rual.nl/en/nano" locale: en alternate: "https://rual.nl/nano" updated: 2026-08-12 source: "https://rual.nl" --- *Core Nano* # Your app, your data, your building. One box, €25 a month. Core Nano is a complete application platform in one small machine: database, accounts, file storage, deployment and the Flow Editor, running on hardware in the Netherlands. You build the application. Everything behind it comes with it. [Start 30 days free](https://rual.nl/en/nano#apply) [See what you get](https://rual.nl/en/nano#what-you-get) ![Screen recording of the Flow Editor: blocks are dragged onto the canvas and connected to one another.](https://rual.nl/site-assets/_opt/blueprint-960.webp) - **€25** per month, fixed - **30** days to try it, free - **NL** hosted in the Netherlands, on our own hardware ## What you get Everything behind your app is already there. Six things you would otherwise assemble, pay and babysit separately. - **Backend and flows** — The database is built in and the Flow Editor sits on top. Your logic runs as blocks you can see, in the same database your app reads from. - **Accounts and login** — Users, roles and login screens are built in. No Auth0 or Clerk with an invoice of its own beside it. - **File storage** — Uploads, documents and images live next to your records, on the same machine, under the same backup. - **Deployment** — Put a version live and it runs. Rolling back is just as fast. No pipeline to babysit. - **Infrastructure** — No servers to rent, size or patch. Nano is the server: one box, yours or one we set up. - **Security** — Encryption, request logging and automatic IP bans are on from day one. The same stack that runs our production clusters. ## Fixed, in a metered world You can assemble this stack yourself. This is what that costs, with list prices and plan names attached. The floor is $45 against €25, roughly half. The real difference is what happens next: the middle column has no ceiling, the right one is simply done. One year, per month. The dashed line is a metered stack doing what metered stacks do: growing with your traffic, from a $45 floor. The flat one is Nano. Illustrative, but the shape is the point. - Assembled separately ($): ≈ $92 and climbing - Core Nano (€): €25, fixed | What you need | Assembled separately | Core Nano | | --- | --- | --- | | Postgres database | Supabase Pro, $25/mo, 8 GB disk | ✓ included | | Auth, up to 100k users | Supabase Auth, inside that $25 | ✓ included | | File storage | Supabase, 100 GB inside that $25 | ✓ included | | Deploy and hosting | Vercel Pro, $20/mo per developer seat | ✓ included | | Monitoring and logs | Inside Vercel’s $20 credit, then metered | ✓ included | | Daily backups | Supabase Pro, 7-day retention | ✓ included | | Local devices over Zigbee, Z-Wave and Matter | Not available at any price | ✓ included | | Total | $45/mo floor, $60 to $75 in practice, no ceiling | €25/mo, fixed | List prices, checked in August 2026. Dollars and euros side by side on purpose: that is how those invoices arrive. **studio.rual.nl · Flow Editor** One flow the way the editor shows it: a sensor and a business record, two blocks apart. - `deur.contact` — trigger · door contact opens - `rooster.check` — outside opening hours? - `incident.log` — writes a record, same database - `mssgs.push` — push to the owner’s phone **execution · Friday 21:47** - `00:00.000` deur.contact · door opened at 21:47 - `+40 ns` rooster.check · outside opening hours - `+1.1 µs` incident.log · record #1,812 written - `+0.3 ms` mssgs.push · push sent to 1 device - `✓ done` flow executed · 4 blocks in 0.3 ms runs: locally, no cloud needed ## The devices in your building join in. Zigbee, Thread/Matter and Z-Wave over USB dongles, plus Philips Hue and Daikin over the local network. Roughly 4,000 device types, because Nano reads Zigbee2MQTT’s device descriptions instead of keeping a list of its own. One vocabulary across protocols: a flow written for an Aqara on Zigbee works against a Fibaro on Z-Wave. And it keeps working without internet. And because Nano is simply Core, everything runs on the same block library: over 4,000 blocks, from Exact, Mollie and Floriday to native AI connections that read images and recognise faces. What hangs on your door today can talk to your invoicing tomorrow. ### The workshop, 17:58. The last order of the day is picked. The same flow that already prepared the invoice now switches the workshop lights and heating off, and checks that the overhead door is shut. Tomorrow morning the picking list is ready and the workshop is warm before you walk in. No separate system for the building, no second dashboard: the building is simply a block in the flow. **One evening of setup, then it is yours.** You need one USB dongle per protocol at about €40 (Zigbee or Thread, never both at once), and devices are adopted once. It is not a certified alarm system and it replaces none. What you get back: no subscription on your own devices, no cloud watching along, and a building that talks to your orders. ### Want the wiring? The tutorial walks the whole setup: dongle, broker, first device, first flow.

When one application becomes five, or 25 users become 250, you grow into a Core licence, from Starter at €515 a month, with the cluster in Ede, the SLA and the support relationship that price includes. Everything you built comes along. [See the licences](https://rual.nl/en/pricing) ## Apply for the trial Thirty days, on us.
