If your flow is more linear looking than a complex DAG and you want to get a full featured webeditor (with lsp), automatic dependency handling, typescript(deno) and python support, I am building an OSS, self-hostable airflow/airplane alternative at: https://github.com/windmill-labs/windmill

You write the modules as normal python/deno scripts, we infer the inputs by statically analyzing your script parameters and we take care of the rest. You can also reuse modules made by the community (building the script hub atm).
