A self-hostable Drive — files, folders, quotas, sharing — with three things most "drop a file" tools don't have.

Quick-Upload opens a temporary drop zone on any device from a code — no login — with optional password, expiry and usage limit. Remote-Upload makes the server fetch a link itself, so a phone on a metered connection never relays the bytes. Hybrid encryption is a choice made per folder: encrypted at rest so the antivirus can still scan the file, or a zero-knowledge vault encrypted in the browser that the server cannot read at all.

Shared Spaces are encrypted server-side only, because a zero-knowledge vault cannot be shared — that trade-off is written in the docs rather than left for you to discover. Same for the rest: background work runs inside the API process to keep a deployment to a single moving part, with Redis/BullMQ documented as the upgrade for horizontal scale instead of required up front.

The software a small company runs its day on: quotes, invoices, accounting, customers, stock, staff, shop — and the website that fronts it.

Around twenty applications sharing one set of customers, one accounting ledger and one search index, so an invoice, the stock movement behind it and the ticket about it are the same object seen from three places. Each company also gets a public website it edits itself, built from blocks, served from its own domain.

The isolation is structural rather than a filter: every customer gets its own copy of the database schema, so one company's data can't turn up in another's query even if a WHERE clause is forgotten. What it costs is honest to state — a schema change has to be replayed on every customer, which is where the 182 tenant migrations come from, and why a deployment stops instead of running new code against a database that hasn't caught up.

The platform Forge Network runs on: client projects and invoicing, server hosting, software licensing and a store.

OPUS Cloud rents out servers with a console, a web file manager and backups in the browser. A Cloud Box behaves like a small VPS — SSH, a persistent home directory, your own packages — but it isn't a virtual machine: the sandbox refuses the privileges a normal SSH daemon needs, so the box ships its own lightweight root filesystem and SSH server instead. Docker doesn't run inside it and only the home directory survives a rebuild. Both limits are on the page, not discovered after signing up.

Forge Licensing issues the licence keys for the group's software. Every answer is signed, so an application can verify a licence without calling home and a captured answer can't be replayed as a valid one. Elipse RSAI runs on it.

A Discord bot that server owners extend themselves — by drawing what they want, not by writing code.

The usual bot features — 93 commands, levels, moderation with an AI pass, premium tiers — plus a visual editor where a module is a diagram of blocks. Nothing is compiled: the editor saves a graph and one interpreter walks it at runtime, so a server owner can build a ticket system or a role menu without touching a line of TypeScript.

The hard part was never the editor. A button posted in a Discord channel outlives the process that posted it, so every component is written to the database and restored when the bot boots — without that, each restart leaves dead buttons in old messages. That, and the fact that Discord's limits (five buttons a row, five rows a message) have to be enforced in the editor rather than discovered by the user when the message fails to send.

_{Least flattering number on this page, and it stays: 2.07× more lines were written than survive. The visual editor was rebuilt more than once.}

A field app for the health referents who follow French nurseries — on the phone, in the car, with no signal and no account.

A referent covers 5 to 30 nurseries and owes each one a number of hours set by decree, split by quarter, and has to be able to prove it. Between two visits it gets written on a notepad, or not at all, and reconstructed in December. The app logs a visit in three taps, keeps four counters per nursery, and flags the quarter that is drifting — the quarterly minimum is the one people miss, you can reach the annual total and still be short on three quarters. It then writes the paperwork — visit reports, referral letters, care plans, annual review — as PDFs, offline.

Nothing leaves the device, and that is a consequence rather than a preference. Records naming a child are health data; hosting them in France requires a certification well out of reach for a project this size, so the hosted version was dropped and the server removed entirely. The bill lands on synchronisation: with no server to reconcile against, two devices sync directly over the local wifi, or through an encrypted file on a USB stick when the nursery network keeps them apart — which it often does.

_{Local database with sensitive fields encrypted · devices paired by QR code and a six-digit code read out loud · PDF engine written in Dart, no network · the only outbound call checks the licence and carries no data about anyone · an expired licence drops the app to read-only and never holds the records hostage}

A clipboard assistant that stays in the background. A hotkey grabs the selection from whatever application is in front, sends it to Gemini and pastes the answer at the cursor — falling back to another model when a quota runs out.

A Minecraft Fabric mod (1.21, Java 21) inspired by Kenshi: capture built as a state machine — free, knocked out, imprisoned, enslaved — with cages, a control scepter, escapes, rebellions, and gamerule switches so it can't be used to grief a server.

An older one. A console-style layer for the TV, navigable entirely with an Xbox controller, that launches local games and media — bridged to Windows through a Python hotkey listener.

Gaming and office setups need different mice and different speakers. Two PowerShell scripts on one key: MouseMode swaps the Windows pointer profile, AudioSwitcher changes the default output and moves every running application onto the new device.
