Develop scripts, query wiki databases, and run basic bots in a Jupyter notebook environment. Experiment and practice in PAWS to learn about Wikimedia APIs and data structures before you start building your first tool or bot.
If your tools support Wikimedia projects, you can host them for free on the Toolforge platform. Toolforge provides scalable shared hosting with job processing, data storage, support for collaboration, and access to wiki database dumps and replicas.
