A week of outside use: seven findings, five fixes https://shreypdev.github.io/undra/blog/a-week-of-outside-use/ https://shreypdev.github.io/undra/blog/a-week-of-outside-use/ Sat, 03 Oct 2026 00:00:00 GMT Field notes A team tried Undra for a week and sent seven findings. Five are fixed, each with a decision record and a review; two were not taken on, and why. Fifteen levers: the JavaScript runtime at 16 KB https://shreypdev.github.io/undra/blog/the-javascript-runtime-at-16-kb/ https://shreypdev.github.io/undra/blog/the-javascript-runtime-at-16-kb/ Sat, 03 Oct 2026 00:00:00 GMT Performance How what a hello-world page loads up front of @undra/runtime went from 22,100 to 15,774 bytes gzipped without removing a feature. Undra 1.0: one Rust core under native apps https://shreypdev.github.io/undra/blog/undra-1-0/ https://shreypdev.github.io/undra/blog/undra-1-0/ Sat, 03 Oct 2026 00:00:00 GMT Launch What Undra is, who it is for, what is in 1.0, how to try it in five minutes, and what it is not. Why Undra is the default choice https://shreypdev.github.io/undra/blog/why-undra-is-the-default-choice/ https://shreypdev.github.io/undra/blog/why-undra-is-the-default-choice/ Fri, 02 Oct 2026 00:00:00 GMT Overview A sourced matrix of what KMP, UniFFI, Flutter and React Native stop you doing, what Undra solved and how, what it costs to adopt, and what is still open. Reads never cross the boundary: how Undra's state model works https://shreypdev.github.io/undra/blog/reads-never-cross-the-boundary/ https://shreypdev.github.io/undra/blog/reads-never-cross-the-boundary/ Wed, 30 Sep 2026 00:00:00 GMT Architecture How Undra mirrors Rust state into SwiftUI, Compose and React: change-sets, keyed lists as recorded operations, a schema-hash gate, and what it all costs. Undra vs Kotlin Multiplatform: sharing logic without leaving your platform https://shreypdev.github.io/undra/blog/undra-vs-kotlin-multiplatform/ https://shreypdev.github.io/undra/blog/undra-vs-kotlin-multiplatform/ Wed, 30 Sep 2026 00:00:00 GMT Comparison Undra and Kotlin Multiplatform both share logic and keep the UI native. A dated, sourced comparison: iOS, web, reads, tooling, ecosystem and team fit. Undra vs UniFFI and Crux: three ways to put Rust under a native app https://shreypdev.github.io/undra/blog/undra-vs-uniffi-and-crux/ https://shreypdev.github.io/undra/blog/undra-vs-uniffi-and-crux/ Wed, 30 Sep 2026 00:00:00 GMT Comparison Three ways to put a Rust core under SwiftUI, Compose and React: UniFFI bindings, Crux's Elm-style core, and Undra's mirrored state. Dated and sourced. Why Undra keeps your UI native https://shreypdev.github.io/undra/blog/why-undra-keeps-your-ui-native/ https://shreypdev.github.io/undra/blog/why-undra-keeps-your-ui-native/ Wed, 30 Sep 2026 00:00:00 GMT Thesis Shared UI and shared logic are different bets. What Flutter, React Native and Compose Multiplatform trade, who should pick which, and where Undra stops.
