InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
That's basically it. The list of supported templates is short, but adding new macros is not a big deal due to the clean architecture I've used :) If you have an idea — just submit an issue.
Technically, the bot is written in Kotlin using Ktor and Koin. It's a single endpoint web service, listening for Telegram Bot API webhooks. Text is drawn using Oswald font (I need Cyrillic, not supported in Anton) with Skija library, a Java wrapper for Skia, a 2D library powering your phone and browser. It is really cool and next time you need to make something with graphics, consider using Skia and its wrapper for your language. Next, generated images are upload to Imgur via its API (the documentation could be better). The whole thing is running on a free VM in Oracle Cloud. So, yeah, next time you need to host something lightweight — check out their offering. Oracle also provides a free DB instance, which I'm using to cache the links. Monitoring: Grafana Cloud (also free). Deployments: GitHub Actions + Ansible. So it didn't cost me a penny, except for ~50 hours of coding in two weeks on the evenings.
