PropFix

Building maintenance and inspections you actually own.

Raise a job against a unit, cost it, close it — and settle move-out damage with ingoing/outgoing inspection comparison instead of an argument. One static binary, one SQLite file. No cloud account, no subscription, no external service.

What is PropFix?

Maintenance and inspection software for people who look after property — managing agents, landlords with a portfolio, body corporates, facilities teams.

It runs as one binary and one SQLite file. A tablet, a laptop, an office NAS or a Raspberry Pi is a complete deployment. Copy the file, run it, done.

Two things it does that general ticketing tools do not:

Costs are per door, not per ticket. Every job belongs to a unit, and spend and labour aggregate per building and per unit. Units are real records with a normalised key, so Flat 3A, 3A and flat 3a are one door rather than three rows quietly fragmenting your reporting.

Inspections compare. Run an ingoing condition report at move-in and an outgoing one at move-out, and PropFix diffs them item by item — what changed, in which direction, and what degraded. Damage liability becomes evidence rather than a disagreement.

Screenshots

Jobs board — triage across every building, filter by unit, priority or assignee.	Job detail — append-only costs and hours, and an event thread with a tenant-visible toggle.
Reports — spend and labour per building and per unit, computed from the ledger every time.	Move-out walkthrough — a condition scale per item, not a checkbox, with the ingoing record alongside.
Inspections — ingoing and outgoing pairs per unit, scheduled and tracked.	Buildings and units — units created on first use, normalised on entry.

_{Light and dark shots of every surface are in docs/SCREENSHOTS.md. All are captured from the real binary in demo mode by npm run screenshots — nothing is mocked up.}

Quick start

git clone https://github.com/vul-os/propfix && cd propfix
npm install && npm run build          # build the app
bash scripts/build-embedded.sh        # compile it into the binary
./backend/propfix --demo              # http://localhost:8080

Demo mode runs entirely in memory with a seeded portfolio — no database, no configuration, nothing written to disk. Sign in as [email protected] / demopassword.

For a real deployment:

./backend/propfix --db /var/lib/propfix/propfix.db --addr 0.0.0.0:8080

The first account you register becomes the owner; registration then closes, and further accounts are created by an authenticated operator. See SELFHOST.md.

Loading

The building is the authority. Whoever manages a building owns its jobs, its job numbering and its inspections. Because the only contended decision — who does the work — has exactly one legitimate writer, there is no consensus protocol, no leader election and no distributed lock anywhere in the system.

Money and hours are append-only. A job's cost is SUM over its ledger at read time, never a stored column. Two people costing the same job while offline therefore add rather than overwrite, and a correction is a negative entry, so the audit trail is complete by construction.

Peers are enrolled by hand. No discovery, no rendezvous, no hub. An operator enters another node's URL; requests are mutually signed with Ed25519. For sites with no connectivity, each node appends only its own ops-<node>.jsonl to a shared folder — so a NAS or a USB stick is a valid transport with no possibility of a write conflict.

Status

Honest per-area accounting. A feature that silently does nothing is worse than one that says it is not built.

Area	State
Jobs — raise, triage, assign, cost, close	Built
Buildings and units, unit normalisation	Built
Append-only cost and time ledgers	Built
Reports — per building, per unit	Built
Inspections — condition capture, completion	Built
Ingoing/outgoing comparison	Built
Auth, org scoping, first-run registration	Built
Peer sync — HTTP transport, Ed25519 envelopes, folder/USB	Built, not yet exercised beyond its test suite
WRAP trades/v0 binding	In progress — cross-organisation work orders
Tenant portal	Designed, not built. The data model carries public vs internal event visibility; there is no tenant-facing surface yet
Photo attachments	Partial — references exist; content-addressed blob storage and replication are not built
Template versioning	Open question. Comparison tolerates template drift by pairing on item text; there is no formal versioning
Recurring / planned maintenance	Not built
Compliance certificates	Not built

Configuration

Flag	Default	Description
--db	propfix.db	SQLite file path
--addr	:8080	Listen address
--demo	off	In-memory demo data; forces :memory: so it can never touch a real database
--sync-listen	off	Accept sync from enrolled peers
--sync-peer	—	Peer URL to sync with
--sync-folder	—	Shared directory for file transport

Every networked feature is off by default. A fresh install makes no outbound connections.

Issues and pull requests welcome. Read ARCHITECTURE.md first — several of its rules (append-only money, building-as-authority, author-key tie-breaks) look like style preferences and are not.
