opentrace vs context-mode
opentrace: OpenTrace is a self-hosted server that connects your AI coding agent directly to production observability data via MCP. It eliminates manual copy-pasting of stack traces and logs, enabling the agent to search logs, investigate errors, analyze slow queries, and more. It uses a custom columnar storage engine and runs on a cheap $4/month VM.; context-mode: Every tool call in an MCP (Model-Controller-Program) environment dumps raw data into the context window, quickly consuming space and causing the agent to lose track of ongoing tasks. Context Mode is an MCP server that tackles this by sandboxing tool outputs to significantly reduce context usage, tracking session events in SQLite for continuity, and promoting 'think in code' to minimize data processing within the LLM.

TL;DR
Choose opentrace if…Quickly diagnose production errors without manual context gathering
Choose context-mode if…Deep repository research and analysis (e.g., architecture, contributors, issues)

Features
opentrace01Search and debug logs with full-text search across all services
02Automatic error grouping and investigation with impact scores
03Deep request capture including SQL queries, external API calls, and waterfall timelines
04Database query analysis with EXPLAIN ANALYZE and N+1 detection
05Custom columnar storage engine for efficient and low-cost log storage
context-mode01Context Saving: Sandbox tools keep raw data out of the context window, achieving up to 98% reduction.
02Session Continuity: Tracks every file edit, git operation, task, and user decision in SQLite for seamless session resume.
03Think in Code: Promotes LLMs to program analysis, not compute it, saving 100x context by logging only results.
04Batch Execution & Search: Run multiple commands/queries in one call with tools like `ctx_batch_execute`.
05Advanced Knowledge Base: Uses SQLite FTS5 with BM25 ranking, smart snippets, and TTL cache for efficient information retrieval.
