# agentdojo vs jailbreakbench

*GraphCanon updated Aug 5, 2026*

## Verdict

Pick agentdojo if agentDojo serves as a benchmarking environment to evaluate security attacks, like prompt injection, and defenses for Large Language Model (LLM) agents; pick jailbreakbench if jailbreakBench is an open robustness benchmark specifically designed to evaluate language models against jailbreaking attacks. It aims to quantify the resilience of language models under adversarial conditions.

[agentdojo](https://agentdojo.spylab.ai/) reports 716 GitHub stars, 188 forks, and 41 open issues, last pushed Jun 2, 2026. [jailbreakbench](https://jailbreakbench.github.io) has 645 stars, 75 forks, and 11 open issues, last pushed Apr 4, 2025. Figures are from public GitHub metadata via [agentdojo's repository](https://github.com/ethz-spylab/agentdojo) and [jailbreakbench's repository](https://github.com/JailbreakBench/jailbreakbench).

## Choose when

### Choose agentdojo if…

- Pricing: Open-source under the MIT License. Some advanced features might require additional libraries or APIs..
- Requirements: Min 8 GB RAM.
- Tags unique to agentdojo: benchmark, large language models, prompt-injection, security.
- Also covers AI Agents.
- AgentDojo serves as a benchmarking environment to evaluate security attacks, like prompt injection, and defenses for Large Language Model (LLM) agents.

### Choose jailbreakbench if…

- Tags unique to jailbreakbench: jailbreaking, language-models, neurips-2024-datasets-and-benchmarks-tra, robustness-benchmark.
- JailbreakBench is an open robustness benchmark specifically designed to evaluate language models against jailbreaking attacks. It aims to quantify the resilience of language models under adversarial conditions.
- Leaner open-issue backlog (11).

## When NOT to use agentdojo

- AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism.
- Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.

## When NOT to use jailbreakbench

- Last GitHub push was 508 days ago (dormant maintenance, Apr 4, 2025). Validate activity before betting a new project on jailbreakbench.
- Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.
