I ve been so heads-down building, I completely lost track of the calendar. I woke up this morning, checked my notifications, and realized Datastripes Lens is live on Product Hunt... and it s actually going super well!

If you haven't seen it yet, Datastripes Lens is your personal data analyst, right in your browser.

Let s be honest for a second: It is late 2025. Why are we still reading cutting-edge science on static PDFs formatted for A4 paper?

We have AI agents writing code, autonomous vehicles, and neural interfaces... yet, to understand the latest breakthrough, we still have to download a flat file, squint at static columns, and imagine how a chart would look if the parameters changed.

It s time for a hard reset. Meet Reserif.

We're launching Datastripes Lens: a browser extension that turns any data table into charts and KPIs as you browse, right on the page!

The launch is here on Product Hunt, but you can follow the product also on our webpage!

The traditional consulting model is broken.

Big momentum at Datastripes: our community is expanding fast, and a new wave of users is reshaping how data work gets done.

We re seeing consultants and analytics professionals build entire services on top of Datastripes. Instead of long onboarding processes or heavy tool stacks, they re using Datastripes to deliver insights directly, instantly, and securely.

There are many tools that promise magical data analysis with AI, but businesses don't need charts that appear out of nowhere and hallucinations.

Datastripes, despite having text-to-chart capabilities, doesn't want to be a black magician or an oracle: we want people to approach data in a simple, replicable, and aware way.

A user asked me: Why not just use ObservableHQ?

ObservableHQ is amazing, with its full JS control, reactive notebooks, endless flexibility. But every chart, filter, or ML model means writing code. 

Process 2GB of data right in your browser. No servers, no costs, ultimate privacy.

Data tools today force you to make a choice: speed or security. You either upload your data to a slow, expensive cloud server or deal with clunky, desktop software. We thought there had to be a better way.

We've completely rebuilt our core engine with WebAssembly (WASM), giving you the power of a desktop app right in your browser.

We can all agree spreadsheets are everywhere, but analyzing them is slow and often requires a data scientist. Teams spend more time cleaning data than actually using it. Traditional BI tools are powerful, but overkill for small teams or solo founders.

Our solution: Datastripes.

Just refactored our app's data processing, and the results are staggering. A single, optimized SQL query running on @DuckDB

WASM = 100x performance gain.

What took minutes on a 500MB dataset now runs in seconds inside the browser. The graph speaks for itself.

During a demo, we realized the platform struggled with 200MB+ spreadsheets. So we rebuilt the core logic using WASM analytical databases and synchronized message channels between workers.

The results speak for themselves:

• 500MB datasets ingested in ~2 seconds

• Live charts on 100k+ rows

• Runs smoothly on a regular i7 / 16GB RAM

The problem: We can all agree spreadsheets are everywhere, but analyzing them is slow and often requires a data scientist. Teams spend more time cleaning data than actually using it. Traditional BI tools are powerful, but overkill for small teams or solo founders

Our solution: Datastripes. Upload your Excel or Google Sheets and instantly get:

• Automated insights: trends, anomalies, and patterns highlighted without manual digging

• Instant visualizations: charts and dashboards generated automatically from your data

• Narrated reports: each analysis can become a data podcast explaining your results

• Direct workflow integration: no code, no setup, just actionable answers

Datastripes presents Catalyst

Your goals, fully decoded.

Tell Catalyst what you want to achieve, and it delivers a complete data analysis:

We've added a new Compare Node in Datastripes that turns side-by-side analysis into a one-step flow.

How it works:

Drop in two incoming data nodes.

Most beginners are told to start with SQL. It s structured, powerful, and universal. But it trains you to think in rows and joins, not in insights.

If your goal is to explore, transform, and visualize data, SQL can feel like writing essays before you ve learned the alphabet. Modern tools let you drag, drop, and experiment with flows.

Just dropped a new Alerts UI for Datastripes. It basically spots sketchy stuff in your data and shows you what s up, in like, 5 seconds. No cap.
