How we compare
Competitor data sourced from public pricing pages as of May 2026. All products self-hosted unless noted.
KAPEX is a software license — not a managed service. You deploy it in your VPC on your own infrastructure. Your data never touches our servers. Your infra costs are yours; our pricing covers the KAPEX engine only.
Pre-seed, in an accelerator, or under $2M raised? We offer extended trials and flexible terms for early-stage teams building with LLM memory. Apply here.
