[Context-Engine](https://context-engine.ai) reports 402 GitHub stars, 55 forks, and 7 open issues, last pushed Jul 8, 2026. [GPTCache](https://gptcache.readthedocs.io) has 8.2k stars, 595 forks, and 99 open issues, last pushed Jul 11, 2025. Figures are from public GitHub metadata via [Context-Engine's repository](https://github.com/Context-Engine-AI/Context-Engine) and [GPTCache's repository](https://github.com/zilliztech/GPTCache). | | [Context-Engine](/tools/context-engine-ai-context-engine.md) | [GPTCache](/tools/zilliztech-gptcache.md) | | --- | --- | --- | | Tagline | Agentic Context Compression Suite | Semantic cache for LLMs, integrated with LangChain and llama_index. | | Stars | 402 | 8,194 | | Forks | 55 | 595 | | Open issues | 7 | 99 | | Language | Python | Python | | Adopt for | Context-Engine: Agentic Context Compression Suite for Python | GPTCache is a semantic caching solution for large language models, designed to integrate with LangChain and llama_index, aimed at improving efficiency by reusing previous computations and responses. | | Persona | - | - | | Runtime | - | - | | License | MIT | MIT | | Categories | AI Agents, LLM Frameworks | Data & Retrieval, LLM Frameworks | ## Trust and health _Sourced signals - not a safety guarantee.

Context-Engine: Agentic Context Compression Suite. GPTCache: Semantic cache for LLMs, integrated with LangChain and llama_index.. See the comparison table for live GitHub stats and shared categories. ### When should I choose Context-Engine over GPTCache? Choose Context-Engine over GPTCache when Tags unique to Context-Engine: ai-agents, compression, context-engine, llm-inference; Also covers AI Agents; Context-Engine ships Docker support for self-hosted deployment; When developing AI agents or LLMs that require efficient context handling and compression to optimize performance. ### When should I choose GPTCache over Context-Engine? Choose GPTCache over Context-Engine when Pricing: GPTCache is available under the MIT license, which is free to use for both personal and commercial projects. However, additional features may require the installation of specific libraries, which may,; Requirements: Min 2 GB RAM; Ensure Python version is 3.8.1 or higher.; Additional libraries are automatically installed as needed for extended functionality.; Tags unique to GPTCache: aigc, autogpt, babyagi, chatbot; Also covers Data & Retrieval; When you are working with LangChain or llama_index and want to enhance the efficiency of your large language models by caching responses semantically. ### When should I avoid Context-Engine? If your application doesn't necessitate compression capabilities tailored specifically for AI agents and LLMs. When the project requirements exclude integration with the supplementary technologies and APIs associated with Context-Engine, such as Ollama API or other specific tools mentioned in its topics. ### When should I avoid GPTCache?

When you need a caching solution that supports a wide range of frameworks beyond LangChain and llama_index, as GPTCache's integration is limited to these specific tools. ### Is Context-Engine or GPTCache more popular on GitHub? GPTCache has more GitHub stars (8,194 vs 402). Stars measure visibility, not whether either tool fits your constraints. ### Are Context-Engine and GPTCache open source? Yes - both are open-source projects on GitHub (Context-Engine: MIT, GPTCache: MIT). ### Where can I find alternatives to Context-Engine or GPTCache? GraphCanon lists graph-backed alternatives at [Context-Engine alternatives](/tools/context-engine-ai-context-engine/alternatives) and [GPTCache alternatives](/tools/zilliztech-gptcache/alternatives) ([Context-Engine markdown twin](/tools/context-engine-ai-context-engine/alternatives.md), [GPTCache markdown twin](/tools/zilliztech-gptcache/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/context-engine-ai-context-engine-vs-zilliztech-gptcache.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, Context-Engine or GPTCache? Context-Engine: Steady. GPTCache: Dormant. 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 Context-Engine and GPTCache? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [Context-Engine trust report](/tools/context-engine-ai-context-engine/trust); [GPTCache trust report](/tools/zilliztech-gptcache/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=context-engine-ai-context-engine`](/api/graphcanon/graph?tool=context-engine-ai-context-engine) - 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/_
