TrailBase is gaining attention for its performance benchmarks and innovative architecture using Rust, SQLite, and V8 engine, allowing for sub-millisecond response times. Users have positively noted the incorporation of SQLite in backend solutions, though there are suggestions for more extensive benchmarking against recently updated versions of platforms like PocketBase, which reportedly offer substantial performance improvements. Some comments pointed out the need for clarity on the query API's async nature despite SQLite's synchronous calls, with a preference for synchronous libraries for better performance in certain scenarios. The roadmap ideas have excited users, particularly for potential features like multi-tenancy. There are discussions around the setup of ACL rules for backend APIs resembling a client-side Firebase implementation, with suggestions for a locked-down database approach for enhanced security. Overall, TrailBase is seen as a promising option that addresses contemporary backend needs, especially in performance-sensitive environments.
