Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
claude-cognis
Persistent memory for Claude Code powered by Cognis. Automatically loads relevant context at the start of every session and saves session summaries when you stop — so Claude remembers what you've been working on across sessions. Supports personal memory (private to you) and team memory (shared across your repo). Includes semantic search, codebase indexing, and smart context assembly via MCP tools, skills, and hooks.
velixar
Velixar is a cognitive memory system for Claude Code. It gives Claude persistent memory, a knowledge graph, identity awareness, contradiction detection, and belief tracking across every session, not just session logs, but a full reasoning layer. 6 skills, 1 agent, 40 MCP tools, 5 live resources, and 18 workflow prompts. Claude doesn't just remember what you said, it understands how your decisions evolved, detects when new information contradicts stored knowledge, and maintains a persistent model of who you are and how you work.
