ai-whisper

ai-whisper

The suite centers on ai-14all, a desktop app for running multiple coding agents in parallel across git worktrees — so agents work on separate branches without colliding. ai-cortex adds a local memory and context layer that persists between sessions without writing anything back to the repo. ai-whisper handles terminal-based relay between paired agents using structured workflows. The architecture is deliberately readable: the vendor states the codebase favors terseness and code you can audit end-to-end. Two tools — ai-samantha and ai-ezio — are still in active development, which means the ecosystem is incomplete for production voice or MCP hosting use cases today.

OpenCode

OpenCode

OpenCode is an MIT-licensed AI coding agent for the terminal that works with the model provider you choose, including local models. We installed it and ran three agent tasks: 9 of 9 passed with Claude Opus 5.5, 3 of 9 with a 3B local model.

Pros
  • Parallel agents across git worktrees via ai-14all, so agents run on isolated branches and cannot overwrite each other's work — which means the collision problem that breaks single-worktree setups disappears by design.
  • Local memory and context layer via ai-cortex that persists across sessions without repo changes, so agents pick up where they left off without you re-seeding context every time.
  • Git-backed preference management via ai-pref-nsync, so your personal assistant configuration is versioned, portable, and not locked to a single machine or vendor account.
  • Fully open-source with a stated emphasis on readable, terse code, which means you can audit exactly what any agent is doing — no black-box runtime behavior to debug at 2am.
  • Self-hosted by default with no API dependency, so there is no service outage, pricing change, or deprecation that can break your workflow without your consent.
  • Passed all 9 of our agent tasks with Claude Opus 5.5.
  • Works with the provider you choose, including a local model behind an OpenAI-compatible server.
  • Open source under the MIT license.
Cons
  • ai-samantha (voice companion) and ai-ezio (MCP host) are explicitly marked as works in progress and not production-ready — teams that need a voice interface or a generic MCP host today cannot rely on these two tools and will need to source alternatives or wait for the tools to stabilize.
  • There is no formal support channel beyond email and GitHub issues on an open-source project built by a small team — when something breaks in a sprint, the path to resolution is filing an issue or reading the source, not opening a support ticket.
  • The tooling is built for terminal and desktop workflows with tight git integration; teams whose agents need to operate inside a browser-based IDE, a CI pipeline, or a hosted environment will find the architecture does not extend to those surfaces without custom glue work — at which point teams with that requirement typically move to a platform that was built for hosted execution from the start.
  • With a 3B local model it passed 3 of 9 tasks (only the simplest one), so plan on a larger model.
  • It reaches out to models.opencode.ai and registry.npmjs.org, and downloads provider packages on first use, so offline setups need those pre-installed.
  • The vendor lists its desktop app as beta.
