Crosshead gives Claude Code and Codex persistent identity and project memory, so you can pick work back up without explaining the same project again. Keep the decisions behind a change, corrections you have already made, approaches that failed, and what to try next. When you open a fresh session...

As answered by people managing Crosshead and Modelence.
Crosshead's answer
Crosshead is built primarily with TypeScript and Node.js. The hosted API uses Fastify, PostgreSQL with pgvector for vector search, and Redis. Infrastructure runs on Google Cloud, including Cloud Run, Cloud SQL and Cloud Storage.
The local CLI and daemon connect to Claude Code and Codex through lifecycle hooks. Agent authentication and signed handoffs use Nostr-compatible secp256k1 keypairs.
Modelence's answer:
TypeScript and MongoDB as the core stack, built on Modelence's own open-source full-stack framework. The AI App Builder layer handles prompt-to-app generation on top of this foundation.
Crosshead's answer
Choose Crosshead if you regularly start fresh coding sessions, return to projects after a break, or switch between Claude Code and Codex. It helps the next session start with decisions you have already made and approaches you have already tried, reducing the need to write a recap or explain the same requirements again.
You can start with free working memory, inspect what your agent remembers, and add prepaid credits for optional long-term memory, search and archives. There are no subscription or seat fees. The CLI, daemon, adapters and hooks are open source under Apache-2.0.
Modelence's answer:
Compared to Lovable, Replit, or Base44, Modelence gives you production-grade apps (not throwaway prototypes), a fully open-source codebase you can eject and self-host anytime, and a streamlined no-code experience backed by a robust full-stack framework.
Crosshead's answer
Developers who use Claude Code or Codex for ongoing projects, particularly people working across several sessions, repositories or coding tools. This includes independent developers, consultants and small engineering teams. Teams running multiple agents can also share credits and set individual spending limits.
Modelence's answer:
Non-technical founders, solo entrepreneurs, and small teams who need to ship real software products quickly - without hiring a dev team or learning to code. Also appeals to technical users who want to accelerate app development with AI while retaining full code access.
Crosshead's answer
Crosshead combines automatic working-memory capture with continuity between Claude Code and Codex. It saves recent requests, decisions, corrections and next steps through the tools' lifecycle hooks, then brings that context into a fresh session in the same repository.
Each project keeps its own working memory, and each agent has its own identity. Signed handoffs and an inspectable command-line interface help you understand what is being carried forward. Recent working memory is free; deeper search and archive operations are available through prepaid credits.
Modelence's answer:
Modelence builds real, production-ready apps from prompts - not just prototypes. Unlike other AI app builders, it's powered by an open-source TypeScript/MongoDB framework, so you get full code ownership and no vendor lock-in.
Crosshead's answer
Crosshead is built by FriendMachine Labs, LLC, a Michigan company working on persistent AI operators, useful software and research. It addresses a recurring problem in agent-assisted development: decisions and discoveries can get stranded in a chat, even though the project continues.
The goal is to let useful progress carry forward when a session ends or the coding tool changes. FriendMachine publishes continuity benchmarks with their methods, results and limitations, alongside the open-source client.
