About Tabularly
Built by people who value data privacy and speed, not vendor lock-in.
Tabularly was born from a simple question: Why does analyzing a local file require a cloud account, a subscription, and a privacy compromise? We built a professional SQL workspace that lives in your browser. No cloud. No tracking. No nonsense.

How Tabularly Started
A practical problem turned into a mission to rethink everyday data work.
The Breaking Point
In the professional data world, uploading sensitive data to a third-party cloud can be a compliance nightmare. We saw a massive gap between the need for speed and the requirement for data custody.
A Better Approach
When we began experimenting with DuckDB-Wasm in early 2026, we realized modern browsers could run complex SQL queries locally.
The Goal
We started building a fast, private workspace for everyday data work. Something simple for data profiling and powerful for complex SQL queries.
Who We Are
A U.S.-based team with real experience in data engineering and browser technologies.
Independent Builders
Tabularly is built by a small, independent team of senior data analysts, data engineers, and web developers in the United States. Without VC overhead, we prioritize building professional-grade tools over data monetization.
Practical Engineering
With years of experience managing massive datasets for government agencies and Fortune 500 companies, we've felt the pain of cloud latency and the risks of sensitive data egress firsthand.
Privacy by Architecture
Our expertise in DuckDB and WebAssembly shaped Tabularly's local-first design. We don't just promise privacy; we built an app that can't even see your files.
Our Three Pillars
How we maintain a tool that stays out of your way.
All processing happens in your browser via DuckDB-Wasm. If our website goes down, your open tab still works.
No password to forget. No profile to track. Just a URL and a workspace ready for your files.
We like CSV, TSV, JSON, Parquet, and SQL. No proprietary formats lock you into our ecosystem.
Our Technical Philosophy
Built on modern web standards to ensure your workspace is fast, private, and future-proof.
Most tools still see your metadata. Tabularly can't see your data, your queries, or your results. Your device is the only environment where your data exists.
We leverage DuckDB-Wasm to provide near-native analytical processing. This allows you to instantly run complex SQL on millions of rows without a backend server.
A Model Built for Users, Not Vendors
Modern tools often prioritize recurring revenue over usability. We chose a different path.
Privacy Isn't a Premium Feature
Many tools reserve privacy controls for enterprise tiers. We think privacy should be the default, not an upgrade.
No More Latency Loops
Uploading hundreds of megabytes just to run a simple SQL query wastes time. Local execution means instant results.
No Subscription Tax
You shouldn't need a monthly bill to inspect a CSV. Tabularly is built to be a tool you own, not rent.
Tabularly is developed in the U.S. by an independent team of senior data analysts, engineers, and front-end developers.
We're committed to building high-performance, local-first data tools that respect your privacy.
