Show HN: I built a Lovable Alternative that runs in the browser
Hey HN, we built playplanet.dev, a Lovable alternative that lets you build and run full stack apps entirely in the browser, no server needed. We run it on a Linux like system compiled to WebAssembly and then use a runtime on top of it. Currently we support frameworks like Astro, React, Angular, Vue and Svelte. You connect your own OpenRouter account and use it to build out the code with an LLM, so there’s no markup fee on our side. Every app you publish is open source under the MIT license, and

Version & cost evidence
Source votes: 1 votes (Oct 28, 2026 UTC; cumulative since publication); previous same-scope observation: 1 (Oct 28, 2026 UTC). These observations do not establish demand growth. Recent records to compare: “Replicate” (Product Hunt, Nov 13, 2026); “Show HN: Autoresearch, but for Weight Space Programming” (Show HN, Nov 13, 2026). Shared themes are navigation hints; they have not been verified as the same need or independent corroboration.
Who is affected
Identify the existing workflow this change affects before recommending an upgrade. Launch attention does not establish improvement; an API, pricing or availability change may instead create migration work.
Missing comparison points
Missing checks: old versus new behavior, affected plans and regions, availability date, compatibility, rollback path and cost under the same workload.
Migration check
Save the release or policy notice, run the same task on the old and new option, and compare outputs and the full bill. For retirement notices, verify the deadline before scheduling migration.
