Feature-by-feature comparison
Verdict
Use n8n for scheduled, linear workflows (daily competitor reports, weekly content research, lead enrichment pipelines). Use LangChain for interactive agent applications (chat with search, research assistants, autonomous agents). They can also work together: n8n for scheduling and orchestration, calling a LangChain agent as an HTTP endpoint.
Consider Scavio instead
Scavio integrates with both: an HTTP Request node in n8n (POST to the endpoint for the platform you want -- api.scavio.dev/api/v2/google for Google, /api/v1/reddit/search for Reddit, and so on) and the langchain-scavio package in LangChain. Same API key and credit pool regardless of which platform triggers the search.

n8n is priced at Self-hosted free; Cloud from EUR 24/mo (2.5K executions). LangChain is priced at Open-source (free); LangSmith from $39/mo. The better value depends on your usage volume and feature requirements.
Scavio integrates with both: an HTTP Request node in n8n (POST to the endpoint for the platform you want -- api.scavio.dev/api/v2/google for Google, /api/v1/reddit/search for Reddit, and so on) and the langchain-scavio package in LangChain. Same API key and credit pool regardless of which platform triggers the search.
Some teams use both tools for different parts of their pipeline. However, a unified API like Scavio can replace the need for multiple subscriptions by providing search, content extraction, YouTube, and Amazon data from a single endpoint.
