Chart Studio decommission and generating chart images

I have a personal project in NodeJS that uses Plotly for generating images (png, I think) sending a JSON to the Chart Studio API. Today I tried to generate a chart and saw that it doesn’t work anymore and that the server returns a 301 error. I went to their site and saw this:

It’s been already a lot of work getting these charts working, they have several annotations which are the whole point of the said charts, and now this doesn’t work anymore. Now I don’t know what’s the alternative and the time I tried to reach them a month ago, they just told me to post questions here (they didn’t answer any of my questions regarding their libraries and the queries daily quota at all).

Any ideas, suggestions, possible solutions to this situation? I need something dependable, and I feel like after a lot of work on this and trying to reach them with no results, and now they closing down their service without previous notice, I’ve been let down big time.

Just for the record, there’s a solution that isn’t perfect but usable. I’m using these two combined:

  1. GitHub - striezel/plotly-node-export-server: Node.js server for offline export of Plotly graphs
  2. GitHub - lovell/sharp: High performance Node.js image processing, the fastest module to resize JPEG, PNG, WebP, AVIF and TIFF images. Uses the libvips library.

The customer service or the person on the other side of the contact form didn’t answer any questions when I asked about if it was correct to use the version of the libraries I was using, the daily limit of request to their server, etc. Unfortunately it was totally useless to contact them.
