foundationdb vs tigerbeetle
Distributed databases compared
foundationdb is a distributed ordered key-value database with ACID transactions, while tigerbeetle is designed for financial transactions represented as transfers between accounts. The main difference is scope: foundationdb provides a transactional storage foundation for structured data, whereas tigerbeetle focuses on ledger-style OLTP.
foundationdb: Store Data Reliably Across Distributed Clusters
FoundationDB is a distributed ordered key-value database with ACID transactions, built for structured data across clusters of commodity servers. It suits applications that need transactional correctness and flexible language bindings.
tigerbeetle: Run a Safety-Focused Financial Transactions Database
TigerBeetle is a financial transactions database written in Zig, designed for mission-critical safety and performance in OLTP systems. It provides debit-and-credit account and transfer operations and can run as a single-replica cluster on Linux, with other platforms documented.

Key differences
- foundationdb supports structured data in an ordered key-value model; tigerbeetle models financial activity with accounts, transfers, and debit and credit balances.
- foundationdb applies ACID transactions to all operations; tigerbeetle focuses on safe, performance-sensitive financial transaction processing.
- foundationdb is written in C++; tigerbeetle is written in Zig.
- Both projects use the Apache-2.0 license.
- foundationdb is intended for distributed clusters of commodity servers; tigerbeetle's quick start uses a single development replica, and production cluster setup should be checked in its documentation.
