Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Is Datomic right for my use case?
You can also consider other durable Datalog options like datahike or datalevin which can work either as lib (SQLite style) or in a client-server setup; if you want to play with bi-temporality XTDB is a rock solid option with very good support and documentation.
- Datomic is free

benefits of clojure for web development over Haskell
There are some Clojure-ecosystems things that are pretty cool, too, that you'd probably miss going into Haskell. lacinia is an extremely cool GraphQL library, and there are a variety of interesting datalog-based datastores which are spiritual descendents of Datomic, notably xtdb (formerly crux) and datalevin. Also as noted, you can write the front-end in ClojureScript if you want to, and there are a lot of cool libraries for that as well.

Call for Help - Open Source Datom/EAV/Fact database in Rust.
There are plenty of open source Datomic Inspired databases. Check out https://github.com/juji-io/datalevin and scroll down all the way down to “Alternatives”. There was even the beginning of a rust one by Mozilla: https://github.com/mozilla/mentat
- Datalevin ships performant fulltext search for its KV and Datalog stores

Choice of NoSQL database: XTDB vs MongoDB
Highly recommend you give https://github.com/juji-io/datalevin a chance. You can use it both as a key-value and/or relational datalog store (like datomic) but it’s very simple to set up and blazing fast!

Ask HN: Why are relational DBs are the standard instead of graph-based DBs?
Unlike some other commenters, I agree that graph models are usually a better fit for most data than relational models. There's been some interesting work in recent years developing this idea: in the Clojure world there's Datomic, XTDB, and a host of competitors, all of which build on work from Semantic Web/SPARQL/triplestores and logic programming. Some are even intended to be used as primary datastores: they support some amount of schema and constraints, have well-defined consistency and ACID guarantees, etc. This makes them unlike graph databases like Neo4J and others, which fill an architectural role more like Elasticsearch as a read-optimization tool. Here's an interesting talk making a case for triple-based databases.

benefits of clojure for web development over Haskell
Physicist here. Made a kind of Physics Puzzle Game. The Github Code proofs that you do not need a backend (in a first step you only want to read and not write external files anyway). Here is what you do: 1) Sign up to and install Github, this all important step is taken for granted by any community in any language but never taught to Phyiscists. 2) Decide to use ClojureScript for your game :-) 3) Look at and reproduce the Shadow-cljs quick start 4) Using Git, clone the Shadow-cljs browser example 5) If you do not know Emacs, install VSCode+Calva 6) Understand the following two Paredit operations in Calva: ctrl+right for ForwardSexp and ctrl+left for BackwardSexp. 7) If you come to this point, try to include reagent into the shadow-cljs example. Ask again here for help if needed.

differential-datalog - DDlog is a programming language for incremental computation. It is well suited for writing programs that continuously update their output in response to input changes. A DDlog programmer does not write incremental algorithms; instead they specify the desired input-output mapping in a declarative manner.
