[I initially explored a more traditional stack: Neo4j for the graph database, RabbitMQ for a task queue, and Postgres with extensions for vector search. However, I realised SurrealDB could cover all of these needs, allowing me to consolidate the backend into a single dependency.](https://www.reddit.com/r/rust/comments/1l9ik5w/showcase_minne_a_graphpowered_personal_knowledge/) [I can never go back to Postgres lmao.](https://www.producthunt.com/products/surrealdb/reviews)
SurrealDB fast tracked our progress with all its features. Graph links + Record links + Full text search + Vector embeddings and Vector search + Surreal WASM for offline-ability... just name it!!!! Thanks Surreal team for making it happen!!!!
We replaced 5 backend tools with SurrealDB and scaled to 700,000 users in 8 hours.
[Fantastic! Graphrag, etc handles it all. Solid and fast](https://www.producthunt.com/products/surrealdb/reviews) [I know people love Supabase and Convex is blowing up. But I think SurrealDB is gonna be the real killer. More modern apps really should be using more graph databases as applications need to provide for more and more complex relationships.](https://x.com/jgeofil/status/1935524555541381290)
[So much easier to write advanced queries compared to SQL. Queries are actually readable! Community on Slack is also very helpful and includes SurrealDB developers.](https://www.producthunt.com/products/surrealdb/reviews) [Surrealist’s way of exploring complex data feels simple as its intuitive, fast, and removes the need for complex queries.](https://www.producthunt.com/products/surrealdb/reviews) [Great product, highly recommend](https://www.producthunt.com/products/surrealdb/reviews)
I'm certainly enjoying that I can replace hundreds of lines of Postgres trigger and function code with a dozen characters in a DEFINE statement in SurrealDB.
[The best next-gen multi-modal database that's out there.](https://discord.com/channels/902568124350599239/902568124350599242/1384923187653116145)
SurrealDB has allowed our team to focus more on product and iteration without worrying about database constraints. We can do literally everything we need in SurrealDB.
