[GPTFuzz](https://github.com/sherdencooper/GPTFuzz) reports 604 GitHub stars, 87 forks, and 17 open issues, last pushed Feb 27, 2026. [gateway](https://www.trylon.ai) has 127 stars, 12 forks, and 0 open issues, last pushed Jun 25, 2025. Figures are from public GitHub metadata via [GPTFuzz's repository](https://github.com/sherdencooper/GPTFuzz) and [gateway's repository](https://github.com/trylonai/gateway). | | [GPTFuzz](/tools/sherdencooper-gptfuzz.md) | [gateway](/tools/trylonai-gateway.md) | | --- | --- | --- | | Tagline | Red Teaming Large Language Models with Auto-Generated Jailbreak Prompts | Self-hosted firewall for securing AI applications with guardrails and content moderation. | | Stars | 604 | 127 | | Forks | 87 | 12 | | Open issues | 17 | 0 | | Language | Python | Python | | Adopt for | GPTFuzz leverages auto-generated jailbreak prompts to red team large language models for testing and evaluation. | Self-hosted firewall for securing AI applications with guardrails and content moderation. | | Persona | - | - | | Runtime | - | - | | License | MIT | Other | | Categories | Evaluation & Observability, LLM Frameworks | Evaluation & Observability, LLM Frameworks | ## Trust and health _Sourced signals - not a safety guarantee.

GPTFuzz: Red Teaming Large Language Models with Auto-Generated Jailbreak Prompts. gateway: Self-hosted firewall for securing AI applications with guardrails and content moderation.. See the comparison table for live GitHub stats and shared categories. ### When should I choose GPTFuzz over gateway? Choose GPTFuzz over gateway when License: GPTFuzz is MIT, gateway is Other; Tags unique to GPTFuzz: jailbreak prompts, large language models, red-teaming; When you need to test the robustness of LLMs against potential manipulative input designed to bypass content controls. ### When should I choose gateway over GPTFuzz? Choose gateway over GPTFuzz when License: gateway is Other, GPTFuzz is MIT; Pricing: Open-source with no explicit monetary cost, but requires users to handle infrastructure costs associated with local Docker deployment; Requirements: Min 4 GB RAM; Requires Docker; Docker and Docker Compose are required for deployment; Initial launch takes several minutes due to downloading machine learning models (~1.5GB+) for the first time; Tags unique to gateway: content-moderation, docker-compose, guardrails, pii-redaction; gateway ships Docker support for self-hosted deployment; When you need to self-host a secure gateway for LLM-based AI applications that requires local deployment via Docker. ### When should I avoid GPTFuzz? If your project requires straightforward, uncontroversial testing tools that do not engage with sensitive content control evasion techniques. For general-purpose debugging and optimization tasks where red teaming tactics are not necessary or appropriate. ### When should I avoid gateway? Avoid if you are looking for cloud-managed services, as this tool is designed solely for local or self-hosted environments Not suitable if you require extensive customization beyond the provided policies.yaml file and predefined guardrails for content moderation and security ### Is GPTFuzz or gateway more popular on GitHub? GPTFuzz has more GitHub stars (604 vs 127). Stars measure visibility, not whether either tool fits your constraints. ### Are GPTFuzz and gateway open source? Yes - both are open-source projects on GitHub (GPTFuzz: MIT, gateway: Other). ### Where can I find alternatives to GPTFuzz or gateway? GraphCanon lists graph-backed alternatives at [GPTFuzz alternatives](/tools/sherdencooper-gptfuzz/alternatives) and [gateway alternatives](/tools/trylonai-gateway/alternatives) ([GPTFuzz markdown twin](/tools/sherdencooper-gptfuzz/alternatives.md), [gateway markdown twin](/tools/trylonai-gateway/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/sherdencooper-gptfuzz-vs-trylonai-gateway.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, GPTFuzz or gateway? GPTFuzz: Slowing. gateway: 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 GPTFuzz and gateway? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [GPTFuzz trust report](/tools/sherdencooper-gptfuzz/trust); [gateway trust report](/tools/trylonai-gateway/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=sherdencooper-gptfuzz`](/api/graphcanon/graph?tool=sherdencooper-gptfuzz) - 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/_
