[blast](http://blastproject.org/) reports 776 GitHub stars, 50 forks, and 6 open issues, last pushed May 29, 2026. [claude-mem](https://claude-mem.ai) has 87k stars, 7.5k forks, and 252 open issues, last pushed Jul 9, 2026. Figures are from public GitHub metadata via [blast's repository](https://github.com/stanford-mast/blast) and [claude-mem's repository](https://github.com/thedotmack/claude-mem). | | [blast](/tools/stanford-mast-blast.md) | [claude-mem](/tools/thedotmack-claude-mem.md) | | --- | --- | --- | | Tagline | Open-source VMs-as-a-service | Persistent Context Across Sessions for Every Agent | | Stars | 776 | 86,816 | | Forks | 50 | 7,500 | | Open issues | 6 | 252 | | Language | Python | JavaScript | | Adopt for | - | claude-mem provides persistent context across sessions, leveraging AI to capture and compress agent activity. | | Persona | - | - | | Runtime | - | - | | License | MIT | Claude-Mem is distributed under the Apache License 2.0, allowing it to be freely used in a variety of development and production environments while maintaining clear licensing terms. | | Categories | AI Agents, Inference & Serving, LLM Frameworks | AI Agents, Inference & Serving | ## Trust and health _Sourced signals - not a safety guarantee.

See the comparison table for live GitHub stats and shared categories. ### When should I choose blast over claude-mem? Choose blast over claude-mem when blast is primarily Python; claude-mem is JavaScript; License: blast is MIT, claude-mem is Apache-2.0; Tags unique to blast: browser-automation, llm-inference, python; Also covers LLM Frameworks. ### When should I choose claude-mem over blast? Choose claude-mem over blast when claude-mem is primarily JavaScript; blast is Python; License: claude-mem is Apache-2.0, blast is MIT; Requirements: Requires Node.js v20.0.0 or higher.; Must have the latest version of Claude Code with plugin support.; Auto-installs Bun (JavaScript runtime and process manager) if not already present.; Requires uv (Python package for vector search), auto-installation supported.; Tags unique to claude-mem: ai-memory, chromadb, claude, long-term-memory; When you require seamless and persistent context continuity between different session interactions with Claude Code or other supported agents. ### When should I avoid blast? AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism. Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. ### When should I avoid claude-mem? When working in environments where Node.js v20.0.0 or higher cannot be installed, as claude-mem requires this version to operate. If your specific AI agent or tool does not integrate with the supported frameworks listed (e.g., Claude Code, OpenClaw), making context persistence ineffective for your workflow. ### Is blast or claude-mem more popular on GitHub? claude-mem has more GitHub stars (86,816 vs 776). Stars measure visibility, not whether either tool fits your constraints. ### Are blast and claude-mem open source? Yes - both are open-source projects on GitHub (blast: MIT, claude-mem: Apache-2.0). ### Where can I find alternatives to blast or claude-mem? GraphCanon lists graph-backed alternatives at [blast alternatives](/tools/stanford-mast-blast/alternatives) and [claude-mem alternatives](/tools/thedotmack-claude-mem/alternatives) ([blast markdown twin](/tools/stanford-mast-blast/alternatives.md), [claude-mem markdown twin](/tools/thedotmack-claude-mem/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/stanford-mast-blast-vs-thedotmack-claude-mem.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, blast or claude-mem? blast: Steady. claude-mem: Very active. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for blast and claude-mem? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [blast trust report](/tools/stanford-mast-blast/trust); [claude-mem trust report](/tools/thedotmack-claude-mem/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=stanford-mast-blast`](/api/graphcanon/graph?tool=stanford-mast-blast) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
