Choose deep-research if…
- deep-research is primarily TypeScript; lever is Python.
- Requirements: Requires Docker.
- Tags unique to deep-research: research, ai, o3-mini, gpt.
- Also covers AI Agents.
- deep-research ships Docker support for self-hosted deployment.
- When you need a tool that can refine its topic focus over time through repeated iterations.
When NOT to use deep-research
- When you prefer a language other than TypeScript, as deep-research specifically requires a Node.js environment.
- If your use case does not necessitate the use of both Firecrawl and OpenAI APIs, preferring instead solutions with more API flexibility or that do not require API keys.
Choose lever if…
- lever is primarily Python; deep-research is TypeScript.
- Tags unique to lever: python.
- Leaner open-issue backlog (2).
When NOT to use lever
- Last GitHub push was 1102 days ago (dormant maintenance, Jul 5, 2023). Validate activity before betting a new project on lever.
- Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough.
