Hi HN, excited to share the project I have been working on for the past two years.
Marple was created by engineers for engineers. Marple helps them organize and analyze their sensor data in a more user-friendly way.<p>We’ve all been there: measurement data from an experiment or test needs to be analyzed but the only thing you have is a few data files flying around. You do not have a clue how to open or read the data. So what you do next is open your Python/Matlab/Jupyter Notebook/… and start coding in order to make some sense of the data. We didn’t like that process, so we started Marple to solve this issue.<p>Engineers tend to log data at frequencies from 1Hz to 10kHz and usually log hundreds of sensors at the same time. Data sets usually contain millions of data points. In order to make our web-based data visualization responsive, we had some technical challenges to tackle. We developed our own visualization engine based on PostgreSQL that is able to visualize millions of data points pretty much instantly. This allows us to create an interactive visualization environment which is perfect for data exploration, even for large data sets!<p>This is the second time we show Marple to HackerNews, but since then we made some big steps. We made a pivot to a cloud product and now offer a free version of Marple. Feel free to head over to our website and give it a go. Let us know what you think of it!
Unrelated to the product itself, please make pricing/licensing clear upfront. “Try for free” leads to a page that says “signing up is free”. Great, but what comes after that? Please don’t leave your users guessing.
Looks like plugins available for Matlab/Simulink from the graphic on your intro page.
Didn't see a quick list of supported interfaces - do you support:
Dymola FMI?
Modbus?
What specifically makes it only (or mainly) relevant to “engineers with sensor data”? It seems like it can be broadly useful for any (numeric) time series data ?
This looks pretty useful and I will definitely be trying it out. I see you can upload CSV files for visualizing. Is there a way to send data as it's generated?<p>Another question would it be possible for Marple to use the data locally (or from say my own s3 bucket or database) instead of having to upload it to your servers?
Looks really cool! I work with phone IMU and this looks appealing.<p>We created our own in house infra to manage and visualize the data, but will try to check this out.
