[gateway](https://www.adaline.ai/docs) reports 605 GitHub stars, 26 forks, and 2 open issues, last pushed Jul 29, 2026. [langstream](https://rogeriochaves.github.io/langstream/) has 417 stars, 28 forks, and 3 open issues, last pushed Jan 3, 2024. Figures are from public GitHub metadata via [gateway's repository](https://github.com/adaline/gateway) and [langstream's repository](https://github.com/rogeriochaves/langstream). | | [gateway](/tools/adaline-gateway.md) | [langstream](/tools/rogeriochaves-langstream.md) | | --- | --- | --- | | Tagline | Unified SDK for calling over 200 LLMs | Build robust LLM applications with true composability | | Stars | 605 | 417 | | Forks | 26 | 28 | | Open issues | 2 | 3 | | Language | TypeScript | Python | | Adopt for | Unified SDK for calling over 200 LLMs with production-grade capabilities in TypeScript. | LangStream is a Python-based tool for building robust Language Model (LLM) applications, emphasizing modularity and composability. | | Persona | - | - | | Runtime | - | - | | License | MIT | MIT | | Categories | Developer Tools, LLM Frameworks | Developer Tools, LLM Frameworks | ## Trust and health _Sourced signals - not a safety guarantee.

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 gateway and langstream? gateway: Unified SDK for calling over 200 LLMs. langstream: Build robust LLM applications with true composability.
