Choose giskard-oss if…
- giskard-oss is primarily Python; fact-checker is Jupyter Notebook.
- Requirements: Requires Python 3.12 or higher..
- Tags unique to giskard-oss: llm-eval, agent-evaluation, fairness-ai, ai-security.
- Also covers AI Agents.
- - You need an open-source solution specifically designed for testing LLMs with built-in checks and vulnerability scans.
When NOT to use giskard-oss
- - If you prefer a tool without any potential telemetry data collection, even though Giskard allows opting out, as it could be seen as potentially intrusive despite safeguards.
- - You are working with environments that only support Python versions below 3.12, since Giskard-OSS requires at least Python 3.12.
Choose fact-checker if…
- fact-checker is primarily Jupyter Notebook; giskard-oss is Python.
- Tags unique to fact-checker: python, jupyter notebook.
- Leaner open-issue backlog (0).
When NOT to use fact-checker
- Last GitHub push was 992 days ago (dormant maintenance, Oct 23, 2023). Validate activity before betting a new project on fact-checker.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
