# Evaluate Dex

These pages help you decide whether Dex fits your system. Read them in order, or go straight to your question.

- [Why Dex?](https://docs.superdurable.io/intro/what-is-dex.md) shows the problem with an order process that breaks halfway, and how Dex models it as a Flow of Steps.
- [Dex vs. Databases](https://docs.superdurable.io/intro/compared-to-database.md) builds the same process on a database, then with queues and an outbox, then as a Flow, and lists the duties that stay with you.
- [Dex and Your Database](https://docs.superdurable.io/components/your-database.md) shows how a Step writes to the database you already have, and when to copy Flow data to PostgreSQL.
- [Dex vs. Other Engines](https://docs.superdurable.io/intro/compared-to-durable-execution.md) maps Dex to replay-based engines, journal-based runtimes, and database-backed libraries, and says when another tool fits better.
- [Performance](https://docs.superdurable.io/intro/performance.md) gives measured throughput and latency on one node with S3, what it costs to run, and how to repeat a result.
- [Limits](https://docs.superdurable.io/intro/limits.md) lists what can surprise a team in production, the release status, and the license.
- [Failover and Deploys](https://docs.superdurable.io/concepts/failover-and-deploys.md) shows what happens when the server or a Worker stops, and how to deploy new code while Flows are open.
- [Correctness and Expressiveness](https://docs.superdurable.io/correctness-and-expressiveness.md) gives a machine-checked proof of what a crash can and cannot change, and what Dex can express.
