Lovable turns a prompt into a prototype you can share by link. ArchStage turns a sentence into a scaffolded codebase on your machine — with a full sprint pipeline, version-controllable files, and zero hosting lock-in.
| Capability | ArchStage | Lovable |
|---|---|---|
| Where your code lives | Your local folder | Lovable's cloud |
| Offline capable | Yes — desktop app | No — browser-based |
| Version control | Any git workflow | Built-in, per-project |
| Stack choice | React, Tailwind, Kotlin, Material, vanilla HTML | React + Tailwind only |
| Sprint / phase history | Persistent per project | Chat-style edit log |
| Pricing model | One-time €38 (launch) / €59 | Monthly subscription |
| AI credits | Pay Anthropic directly | Bundled + rate-limited |
| Data privacy | Local-first, no telemetry | Cloud-hosted projects |
| Deploy anywhere | Any host, any platform | Lovable hosting preferred |
ArchStage writes source code to a path you choose. Open it in any editor, push it to GitHub, fork it, archive it, forget about ArchStage — the code stays yours. Lovable projects live inside Lovable; exporting is possible but not the default path.
Each ArchStage project generates a tech spec, an implementation plan, and phase files before any code is written. You can inspect or edit them. Lovable operates more like a continuous chat — great for iteration, harder to audit.
ArchStage ships Kotlin + Material for Android, plus vanilla HTML and desktop tool scaffolds. Lovable focuses on React web apps. If your roadmap includes a mobile app, ArchStage covers that in the same tool.
ArchStage is a one-time purchase for the desktop app. Claude usage is billed by Anthropic directly — no middleman markup, no per-seat tax. Lovable uses recurring monthly pricing with credit limits.
Lovable is excellent for a sharable prototype in the browser. ArchStage is the better fit when the prototype is a starting point, not the product — when you plan to keep iterating, push it to production, and own the files.
