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
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.
io.github.sachitrafa/cognitive-ai-memory
Ebbinghaus-based persistent memory for Claude. Memories decay with time, strengthen on recall.
