{"slug": "solid-2-vs-octane", "title": "Solid 2 vs Octane", "summary": "A developer compared the JavaScript UI frameworks Octane and Solid 2, scoring Solid 2 as the winner in 7 out of 9 categories, including state architecture, reactive reasoning, and async/data flow. The developer noted Octane's strengths in component authoring and ecosystem interoperability, but concluded that Solid's advantages accumulate as applications grow in complexity.", "body_md": "**NOTICE:** I've summarized the perspectives of Octane's and Solid's creators here, for anyone short on time: [https://gist.github.com/aleclarson/829c10aa7d287944ef75e1c2a90bef06](https://gist.github.com/aleclarson/829c10aa7d287944ef75e1c2a90bef06)\n\nI'm a React/Preact/Astro developer with an interest in other renderers. The two that have most caught my eye recently are [Octane](https://octanejs.dev/) (from Dominic Gannaway of React Hooks / Svelte / Inferno fame) and [Solid 2](https://www.solidjs.com/blog/solid-2-0-rc-the-big-reveal).\n\nI asked ChatGPT to compare them with its own [\"Renderer DX Pillars\"](https://gist.github.com/aleclarson/64308585a36fe65692149b9cd2f59475), which I've shared below. This is its gut instinct, with very little hedging:\n\n| Pillar | Winner | Why |\n|---|---|---|\nState architecture freedom |\nSolid 2 |\nReactivity is independent of components. Much less component gravity. |\nReactive reasoning |\nSolid 2 |\nThe dependency graph is explicit and causal. Easier to answer “why did this update?” |\nDerived state & synchronization |\nSolid 2 |\nFine-grained derivation is the native model; less need to coordinate state manually. |\nAsync/data flow |\nSolid 2 |\nThis is basically Solid 2's flagship idea. Async being part of reactivity feels deeper than improving Suspense/hooks ergonomics. |\nComponent authoring |\nOctane |\nNormal values, normal functions, familiar TSX, fewer Solid-specific semantic gotchas. |\nEscape hatches |\nSolid 2, narrowly |\nSolid's primitives compose very directly with imperative JS without pretending everything is a component concern. |\nEcosystem interoperability |\nOctane |\nIf its React-ecosystem compatibility ambitions work, this could be a huge advantage. |\nTooling & debuggability |\nSolid 2 today |\nMore mature and battle-tested. Octane's compiler creates more invisible machinery that tooling has to explain well. |\nArchitectural scaling |\nSolid 2 |\nIts reactive model naturally lets domain/application architecture exist independently of rendering. |\n\nSo my gut scoreboard is:\n\n**Solid 2: 7**\n**Octane: 2**\n\nBut the two Octane wins are meaningful ones.\n\nIts pitch seems particularly strong around:\n\n**“I want React's authoring experience without React's runtime/design baggage.”**\n\nYou get something like:\n\n``` js\nfunction Counter() {\n  const [count, setCount] = useState(0);\n  const doubled = count * 2;\n\n  return <button onClick={() => setCount(count + 1)}>\n    {doubled}\n  </button>;\n}\n```\n\nThat's extremely approachable.\n\nSolid asks you to internalize:\n\n``` js\nconst [count, setCount] = createSignal(0);\nconst doubled = () => count() * 2;\n```\n\nwhich isn't hard, but it is a different programming model.\n\nSo for **day-one DX**, I wouldn't be surprised if Octane feels better.\n\nSolid's advantages seem to accumulate as the application becomes less like:\n\nsome components with state\n\nand more like:\n\na complex reactive application that happens to have a UI.\n\nThat's where signals outside components, ownership, fine-grained derivation, async graph semantics, stores, and independent domain state all start reinforcing each other.\n\nMy gut says the trajectory looks something like:\n\n```\nsmall app\n\nOctane  ██████████\nSolid   █████████\n\n         ↓ complexity\n\nlarge/stateful app\n\nOctane  ████████\nSolid   ████████████\n```\n\nNot because Octane necessarily scales poorly, but because **Solid's abstraction seems closer to the actual problem being modeled** once state relationships get complicated.\n\n**Escape hatches.**\n\nOctane could easily end up winning there if its compiler makes effects, refs, subscriptions and integration code extraordinarily pleasant.\n\nAnd **ecosystem interoperability could become an overwhelming Octane win** if their compatibility layer is genuinely broad and reliable rather than “we have adapters for the popular demos.”\n\nIf I had to assign confidence rather than points:\n\n**Solid strongly wins:** state architecture, derived state, async, architectural scaling.**Solid probably wins:** reactive reasoning, escape hatches.**Octane strongly wins:** initial component authoring.**Octane probably wins:** ecosystem interoperability.**Solid wins for now:** tooling/maturity.\n\nThe biggest question I'd personally want answered before choosing between them is therefore not performance.\n\nIt's:\n\nDoes Octane's compiler actually eliminate the architectural drawbacks of component-centric reactivity, or does it mostly make that model much nicer to write?\n\nIf it's the latter, I'd expect Solid 2 to remain the stronger foundation for complex applications.", "url": "https://wpnews.pro/news/solid-2-vs-octane", "canonical_source": "https://gist.github.com/aleclarson/0f4266d63fd83c7a5ea5512441bbea0c", "published_at": "2026-08-13 22:34:50+00:00", "updated_at": "2026-08-18 04:10:57.204839+00:00", "lang": "en", "topics": ["developer-tools"], "entities": ["Octane", "Solid 2", "Dominic Gannaway", "React", "Preact", "Astro", "ChatGPT"], "alternates": {"html": "https://wpnews.pro/news/solid-2-vs-octane", "markdown": "https://wpnews.pro/news/solid-2-vs-octane.md", "text": "https://wpnews.pro/news/solid-2-vs-octane.txt", "jsonld": "https://wpnews.pro/news/solid-2-vs-octane.jsonld"}}
