Memstate Alternative

Kronvex vs Memstate:
B2B API or Personal Coding Tool?

Q: Is Memstate GDPR compliant?

Memstate does not specify EU data residency or provide a Data Processing Agreement (DPA). Kronvex stores all data in Frankfurt (Supabase eu-central-1) and provides a DPA on request.

Q: Can I migrate from Memstate to Kronvex?

Yes. Export your memories from Memstate and bulk-import them via POST /api/v1/agents/{id}/remember. Contact hello@kronvex.io for a migration guide.

Q: Does Kronvex support MCP like Memstate?

Yes. Kronvex ships an MCP server you can install with npx @kronvex/setup, compatible with Claude, Cursor, Cline, and Windsurf. Unlike Memstate which is MCP-only, Kronvex also exposes a full REST API for backend integrations.

Kronvex is built for production multi-tenant agents with EU data residency and a full REST API. Memstate is MCP-first and designed for personal coding context. Here is how they differ.

Frequently asked

Your questions, answered

Is Memstate GDPR compliant?

Memstate does not publicly specify EU data residency or provide a Data Processing Agreement (DPA). If you are handling personal data of EU residents, this is a significant gap. Kronvex stores all data exclusively in Frankfurt (Supabase eu-central-1) and provides a DPA on request — GDPR compliance is built into the architecture, not an enterprise add-on.

Can I migrate from Memstate to Kronvex?

Yes. Export your memories from Memstate, then bulk-import them via POST /api/v1/agents/{id}/remember — a simple loop over your export file. We can provide a migration script on request. Email [email protected] and we will help you migrate at no charge.

Does Kronvex support MCP like Memstate?

Yes. Kronvex ships an MCP server you can install with npx @kronvex/setup, compatible with Claude Desktop, Cursor, Cline, and Windsurf. Unlike Memstate which is MCP-only, Kronvex also exposes a full REST API — so you can use it from any backend, script, or framework, not just AI coding assistants.
