Great question — variable-length paths are fully supported in the query builder:

# Friends of friends (1 to 3 hops)

    stmt = select().match(
        (User.alias("a"), FRIEND.variable_length(1, 3), User.alias("b"))
    ).where(
        User.alias("a").user_id == 1
    ).returns(
        User.alias("b")
    )

Generates: `(a)-[:FRIEND1..3]->(b)`

*Variants:* - Unbounded: `FRIEND.variable_length()` → `` - Exact length: `FRIEND.variable_length(2, 2)` → `2` - Min only: `FRIEND.variable_length(1)` → `1..` - Range: `FRIEND.variable_length(1, 3)` → `*1..3`

You can also use the explicit `VariableLength(FRIEND, 1, 3)` constructor if you need to alias the path or reference it later in the query.

The builder handles all edge cases (empty paths, cycles) the same way RedisGraph does — we compile to idiomatic Cypher without abstraction leaks. Raw string patterns still work if you need something exotic.

Thanks for sharing these resources — great to see the FalkorDB ecosystem growing! We built GraphORM with a focus on type safety + fluent query composition (e.g., indegree()/outdegree() helpers, chainable .match().where().returns()), which we found missing in existing RedisGraph/FalkorDB Python tooling. Happy to see multiple approaches emerging — diversity helps the ecosystem. We're also planning to expand support beyond RedisGraph/FalkorDB to other Cypher-compatible databases where the query model fits. Would love to exchange ideas on ORM design patterns if you're open to it.

Sure, BTW as you might be aware, RedisGraph support was discontinued, so FalkorDB is maintained with more features and fully supports all RedisGraph features.
