Why people love it

  • Pluggable, extensible design · 2

    It's pretty easy to get started with and has a pretty pluggable ecosystem

    Jun 2026 · comment

    it looked great in terms how everything is an event that you can extend

    Sep 2026 · comment
  • Works with local and non-vendor models · 2

    You can actually run a local model with strands using Ollama pretty easily

    Jul 2026 · comment

    it's the most mature (IMO) that isn't specific to a model provider

  • Easy to start, ergonomic API · 2

What people warn about

  • Benchmark comparison seen as misleading · 2

    it feels disingenuous to compare token usage to a pi setup that injects a bunch of stuff into context

    Sep 2026 · comment

    Technically correct inflating it? Well, that's confidence boosting.

    Sep 2026 · comment
  • Narrow provider support, opinionated design · 2

    Strands is more opinionated and higher-level, also not vendor neutral.

    Jun 2026 · comment

    Supported provider list is nowhere close to pi's or opencode's

    Sep 2026 · comment
  • Unclear value and weak documentation · 2

    Strands documentation seems very underwhelming compared to Mastra

    Jan 2026 · comment

    I have no idea what the value prop for Strands Harness is.
