Open Source Durable Objects for Postgres
summary
Solid Objects implements the Durable Objects programming model as a library that integrates directly with existing SQL databases like PostgreSQL, MySQL, and SQLite. This approach provides a consistent identity, durable state, and ordered execution without the vendor lock-in, unpredictable pricing, or operational overhead associated with proprietary cloud services. By leveraging the database as the source of truth, it eliminates the need for separate stateful systems or complex manual locking mechanisms.
key points
- The library replaces fragmented systems of row locks, Redis locks, and cron-based sweepers with a single object model that handles state and scheduling atomically.
- Execution is managed through an ordered mailbox and a fenced lease system, ensuring that only one process can modify a specific object's state at a time within a single transaction.
- Because it lives in the existing database, it avoids the need for external brokers or daemons, making it easier to back up, monitor, and restore compared to self-hosted alternatives.

Software engineers and architects who want to implement actor-model state management without relying on proprietary cloud providers or managing additional infrastructure.
discussion skeptical
consensus
Commenters generally agree that cloud pricing models are unpredictable and risky for individuals, often lacking necessary hard cost caps to prevent catastrophic bills. While some argue that enterprise-grade tools are not designed for consumers, there is a strong consensus that the source article is poorly written and likely generated by AI, making it difficult to read.
top insight
The tension between enterprise and consumer cloud services stems from a different set of priorities: enterprises prioritize uninterrupted service and scalability over cost caps, whereas consumers require financial safety nets. This explains why providers like AWS avoid hard caps that could inadvertently shut down critical business infrastructure.
