# TigerBeetle Hacker Approved page: https://hackerapproved.com/p/tigerbeetle/ 53 people recommended TigerBeetle in Hacker News comments, 10 had mixed feelings and 4 criticized it, November 2025 to October 2026. It was recommended in 12 of 12 months, in 37 threads. It meets the Hacker Approved badge rule. **Verdict:** Fast, reliable database built for financial transactions, especially batch workloads, with heavy fuzzing and simulation testing. Critics say it is specialized and not a general-purpose database. Summary written by Claude from 52 comments. It was written before the November 2026 recount, and 51 of those comments still count. ## Why people recommend it - Deterministic simulation testing and fuzzing (4 comments in the sample): "They have consistently attributed things like design and deterministic simulation testing to their success and reliability" ([source](https://news.ycombinator.com/item?id=48850854)) "For us, we need to go extra N miles to catch the rest of the bugs as well…" ([source](https://news.ycombinator.com/item?id=46167512)) "Perhaps something like what TigerBeetle does: deterministic simulation testing." ([source](https://news.ycombinator.com/item?id=49756368)) - Fast batch transaction processing (3 comments in the sample): "Tigerbeetle is amazing for moving large numbers of batch transactions at once." ([source](https://news.ycombinator.com/item?id=45884359)) "For batch transactions, Tigerbeetle delivered truly impressive speeds" ([source](https://news.ycombinator.com/item?id=45883391)) "Whereas TB does vectorized concurrency control: read the 2 accounts, update them 8K times, write the 2 accounts." ([source](https://news.ycombinator.com/item?id=45896350)) - Built specifically for financial transactions (3 comments in the sample): "TigerBeetle was built for exactly the type of transactional processing this post is about" ([source](https://news.ycombinator.com/item?id=49234753)) "TigerBeetle seems to be specialized for financial data and to optimize perf/cost ratio." ([source](https://news.ycombinator.com/item?id=47804349)) "To specialize not for general purpose but only for transaction processing." ([source](https://news.ycombinator.com/item?id=45886322)) - Strong correctness and reliability record (2 comments in the sample): "They operate on an entire different level of correctness expectations compared to something like Bun." ([source](https://news.ycombinator.com/item?id=48137738)) "The more you zoom, it’s a stronger set of guarantees in terms of safety and performance." ([source](https://news.ycombinator.com/item?id=47799561)) ## What people warn about - Narrow scope needs custom logic (2 comments in the sample): "They've made some unique choices that work great for them, but it really doesn't seem like they can be universally applied." ([source](https://news.ycombinator.com/item?id=50270347)) "it handles so little you will have to roll a lot of custom logic around it to batch realtime transactions quickly" ([source](https://news.ycombinator.com/item?id=45883822)) - Seen as simple key-value store (2 comments in the sample): "tiger beetle is awesome to keep the account balance. that's it." ([source](https://news.ycombinator.com/item?id=47798983)) "This looks like yet another basic key value store." ([source](https://news.ycombinator.com/item?id=47799446)) - Non-batch performance drop disappointed (1 comment in the sample): "Was there something wrong with our test of the individual transactions in our Go script that caused the drop in transaction performance we observed?" ([source](https://news.ycombinator.com/item?id=45890141)) ## The badge A product earns the Hacker Approved badge when at least 10 people recommend it, recommenders outnumber critics at least 2 to 1 (mixed feelings count toward neither side), it was recommended in at least 4 of the 12 months and in at least 5 different threads, and no single thread supplies more than half of the people who recommend it.
