Each week we review 2—3 of the most interesting developer tools. Here's what we featured this week.
Agent harness & service framework.
Supports a variety of runtime primitives including model routing, memory, tools, guardrails, and durable workflows. Automatically creates MCP gateway. Built-in A2A gateway. All abstractions are Go interfaces to make it easily pluggable. Orchestrates multiple services with a local dev server and deploy tooling.
Encourages microservices, which are often overkill - especially at the beginning of a new project.
Local secret broker.
Local-first secret storage with project bindings to allow access to specific secrets. Can launch apps with the secrets injected or act as a broker with on-demand supply of secrets. Time-bounded grants. First-class support for agents to request secrets. Access auditing.
Local-first is by design in v1, but also a limitation because there’s no control plane or cloud sync.
