Validate activity before betting a new project on langstream. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. ## Common questions ### What is the difference between oterm and langstream? oterm: the terminal client for LLMs. langstream: Build robust LLM applications with true composability. See the comparison table for live GitHub stats and shared categories. ### When should I choose oterm over langstream?

Last GitHub push was Jan 3, 2024 (dormant maintenance). Validate activity before betting a new project on langstream. Developer Tools: A gateway is overkill when you're pinned to a single provider and model. LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. ### Is oterm or langstream more popular on GitHub? oterm has more GitHub stars (2,440 vs 417). Stars measure visibility, not whether either tool fits your constraints. ### Are oterm and langstream open source? Yes - both are open-source projects on GitHub (oterm: MIT, langstream: MIT). ### Where can I find alternatives to oterm or langstream? GraphCanon lists graph-backed alternatives at [oterm alternatives](/tools/ggozad-oterm/alternatives) and [langstream alternatives](/tools/rogeriochaves-langstream/alternatives) ([oterm markdown twin](/tools/ggozad-oterm/alternatives.md), [langstream markdown twin](/tools/rogeriochaves-langstream/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/ggozad-oterm-vs-rogeriochaves-langstream.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, oterm or langstream? oterm: Active. langstream: Dormant. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for oterm and langstream? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [oterm trust report](/tools/ggozad-oterm/trust); [langstream trust report](/tools/rogeriochaves-langstream/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=ggozad-oterm`](/api/graphcanon/graph?tool=ggozad-oterm) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
