leviathan alternatives
Curated alternatives to leviathan — and why you'd switch.
xerj
One Rust binary for agent search: BM25, vector and hybrid search over code, docs, logs and PDFs, an Elasticsearch-compatible API, MCP, and Query-1, which answers by running programs over facts.
Why switchBoth are single Rust binaries that index records so agents get cited, token-cheap answers. Leviathan is a lean full-text CLI; XERJ a full engine with vector search, a server and an Elasticsearch-compatible API.
Full comparison →context-mode
Local plugin for 10 coding agents that runs tool calls in a sandbox, indexes full output in SQLite FTS5 and returns only what the agent asks for — ~99% fewer bytes in context, zero telemetry.
Why switchBoth index big text into a local store so the agent fetches small relevant slices. context-mode indexes tool output; Leviathan indexes your datasets.
Full comparison →headroom
Context compression layer for agents: squeezes tool outputs, logs, files and RAG chunks 20-95% before the LLM — reversible, local-first; library, proxy, one-command agent wrap, or MCP.
Why switchBoth cut tokens spent on bulky data. Headroom compresses what is passed in; Leviathan retrieves only the few matching records.
