TECHNICAL ARCHITECTURE
No clouds. No servers. No "syncing." Just your data, on your computer, under your control. Here's exactly how we make that happen.
CREATE TABLE leads (
id INTEGER PRIMARY KEY,
name TEXT NOT NULL,
email TEXT UNIQUE,
company TEXT,
value DECIMAL,
created_at TIMESTAMP
);
-- Your data. Your schema. Your control.
-- We can't see it. We can't sell it.
-- We can't even touch it.See why our architecture makes SaaS look like a bad joke

They control everything

Your data, their control

YOUR Database
SQLite file on YOUR machine

The technologies that make data ownership possible
The world's most deployed database
SQLite is a self-contained, serverless, zero-configuration database engine. Your entire database is a single file on your computer—portable, standard, and completely under your control.
No servers, no sync, no problem
Traditional SaaS: Your app is just a window into THEIR database. Local-first: Your app IS the database. Every click, every query, every save happens on YOUR machine. No latency. No downtime. No dependency.
# Your database location
~/Documents/Suplex/suplex.db
# Back it up however you want
cp suplex.db suplex-backup-$(date +%Y%m%d).db
No vendor lock-in, ever
Your data isn't trapped in a proprietary format. It's standard SQLite—readable by thousands of tools. Want to switch to something else? Your data comes with you, no conversion needed.

Answering the questions you're probably asking
A: Your database is just a file. Back it up to Dropbox, iCloud, Google Drive, an external drive—anywhere. Unlike SaaS "backups" that you can't actually access, YOUR backup is YOURS.
A: Put your database in a synced folder (Dropbox, iCloud, etc.). Same file, multiple devices. Or use our optional peer-to-peer sync—your data still never touches our servers.
A: Your choice. Keep it on one machine. Sync it everywhere. Access via VPN to your home computer. With SaaS, you have no choice. With Suplex, YOU decide.
A: You keep using the app. Your database doesn't expire. Even without updates, your data remains fully accessible. Try doing that with a SaaS that shuts down.
Query your own database with standard SQL
-- Your data is just a SQLite database
-- Query it with any tool: Python, R, Excel, Tableau...
SELECT
company,
SUM(deal_value) as total_pipeline,
COUNT(*) as lead_count
FROM leads
WHERE created_at >= '2024-01-01'
GROUP BY company
ORDER BY total_pipeline DESC;
-- No API limits. No "contact sales." Just YOUR data.Join the local-first revolution. Your data belongs on your machine—not in someone else's cloud.
