Diesel is a mature, macro-driven typed ORM for Rust with strong compile-time query checking. ruprizzle is a schema-first alternative: you edit a declarative schema file, the CLI diffs it against the last snapshot and writes up.sql and down.sql, and the generated client is plain Rust calling sqlx with .to_sql() on every query builder.
| Feature | ruprizzleSchema-first Rust ORM | DieselTyped, macro-driven Rust ORM |
|---|---|---|
| Schema-first code generation | Yes — schema is the source of truth | No — schema is driven by table structs |
| Declarative schema DSL | Yes — schema.ruprizzle | No — table structs in Rust |
| Type-safe column tokens | Yes | Yes |
| Type-safe nested include | Yes — two-level include with one query per level | No |
| Migrations from schema diff | Yes — migrate dev diffs and writes up/down SQL | No — migrations are authored separately |
| Compile-time query checking | planned | Yes — diesel's strongest feature |
| No hidden query engine | Yes — plain Rust calling sqlx | Yes — generated SQL, no sidecar |
| .to_sql() on every query builder | Yes | No |
| Postgres + SQLite support | Yes, from day one | Yes |
| Built on sqlx | Yes | No |
| Maturity | Beta — 0.4.0-beta.2 | Stable and widely adopted |

Choose ruprizzle when you want the schema as the single source of truth, automatic migration diffing from that schema, and the ability to inspect the exact SQL that will run on every query builder. It is built for teams that prefer schema-first code generation and SQL transparency over hand-written table structs.
Choose Diesel when you need a stable, mature ORM with excellent compile-time query checking and a large ecosystem. Diesel is the safer choice for teams that value stability over the newest features and do not mind writing and maintaining table structs and migration files separately.
ruprizzle is younger and still in beta, so it has less ecosystem support and a smaller community. Diesel is more mature but is schema-second: the schema and the Rust table structs can drift, and migration SQL is authored by hand rather than generated from a diff.

Not yet. ruprizzle is at 0.4.0-beta.2. The core is complete and published on crates.io, but the public API is still stabilising. Known gaps are documented rather than hidden.
You could, but there is no reason to. They are both full ORMs. Choose one based on whether you want schema-first generation and SQL transparency (ruprizzle) or a mature, compile-time-checked macro ORM (Diesel).
