Autocomplete that follows your fields through the stages that reshape them.

What it does

• Field paths, types, operators, stages, accumulators and enum values, taken from the collections you are connected to
• The pipeline is folded stage by stage, so a field an earlier stage created is still offered eight stages later. $project, $group, $count, $facet, $bucket and $unset reshape the result, $addFields, $set and $lookup add to it
• $lookup pulls in the foreign collection schema, nested paths included
• A JavaScript sandbox with BSON constructors, fetch, crypto, Faker, Luxon, Day.js, Lodash and Zod
• Build a pipeline stage by stage with drag and drop and a live preview, or write it as code. The two round-trip a pipeline the builder can read, and reduce one it cannot
