GripTape vs Hermes Agent: Agent Frameworks Comparison

GripTape is a modular Python framework for building AI agents and workflows with chain-of-thought reasoning capabilities. Founded in May 2023 by former Amazon Web Services employees in Seattle, GripTape was acquired by The Foundry Visionmongers on February 18, 2026. The company raised $12.5 million and grew to 22 employees before the acquisition, focusing on helping developers and creatives harness the potential of LLMs in secure, professional production environments.

GripTape offers multiple products to serve different user needs: the GripTape Framework is a Python toolkit enabling developers to build secure GenAI applications and agents; GripTape Nodes provides a visual interface allowing artists to build AI-driven workflows without writing code; and GripTape Cloud offers managed services for deployment. The framework is designed with a robust, highly extensible architecture for scale, workflow longevity, and integration with existing production infrastructure including management systems and render farm hand-offs.

Following the Foundry acquisition, GripTape's capabilities are being integrated into Foundry's creative software portfolio, enabling visual effects, animation, and design professionals to orchestrate multiple AI models and agents within their existing workflows. The core framework remains available under the Apache 2.0 open-source license, ensuring continued community development while gaining the backing of an established creative technology company.

Hermes Agent is Nous Research's open-source autonomous AI agent with persistent memory — released February 2026 and the fastest-growing agent framework of 2026, hitting 95.6K GitHub stars in seven weeks. Unlike most agents that forget everything between sessions, Hermes maintains a curated memory of preferences, projects, environment, and lessons learned.

The memory system is layered: MEMORY.md and USER.md files live in ~/.hermes/memories/ and inject into the system prompt as a frozen snapshot at session start. On top of this, Hermes ships 8 external memory provider plugins — Honcho, OpenViking, Mem0, Hindsight, Holographic, RetainDB, ByteRover, and Supermemory — adding knowledge graphs, semantic search, automatic fact extraction, and cross-session user modeling.

Hermes also auto-generates skills: as the agent solves novel tasks, it captures the procedure as a reusable skill. Nous Research benchmarks show agents with 20+ self-created skills complete similar future tasks 40% faster (in tokens and time, not necessarily quality). The improvement is domain-specific — skills don't transfer across domains. Hermes is fully open-source and self-hostable, positioned as the agent that compounds in value the longer you use it.
