Agent Development Kit (ADK) vs agentmemory

Agent Development Kit (ADK) and agentmemory are both agent frameworks tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

Agent Development Kit (ADK)

ADK is the open-source agent development framework that lets you build, debug, and deploy reliable AI agents at enterprise scale.

agentmemory

Orbit is an open-source agent orchestration harness that wraps coding agent runs in bounded, dependency-ordered tasks, then gates task completion on real validation: tests, lint, and type checks must pass before an orbit closes. Every run produces structured JSON artifacts — agent output, rubric scores, accept/iterate/stop recommendations, and a human-readable progress log — so you have a trail to review, not just a diff to guess at. It runs against Claude, Codex, Cursor, or any agent that speaks JSON over CLI. The demo runs without an API key, which matters when you're evaluating whether it even fits your workflow. Where it strains: teams who need a web UI, multi-agent parallelism, or cloud-managed infrastructure will hit the limits of an intentionally small CLI harness fast.

Pros	Context is treated like source code with structured assembly of sessions, memory, tool outputs, and artifacts, automatic filtering of irrelevant events, summarization of older turns, lazy-loading of artifacts, and token usage tracking to keep agents fast, efficient, and reliable by default Multi-language support with Python, TypeScript, Go, and Java implementations Model-agnostic and compatible with other frameworks while optimized for Gemini Built-in development UI for testing, evaluating, debugging, and showcasing agents When deploying to Google Cloud, agents inherit managed infrastructure, built-in authentication, Cloud Trace observability, and enterprise-grade security without code changes	Validation gates tied to your actual test suite and linter — not a model's self-report — which means a task cannot be marked complete when the code still breaks your build. Structured JSON artifacts on every run (agent output, rubric scores, review recommendation, progress log), so you have inspectable evidence for human review instead of reconstructing what the agent did from a diff. Agent-neutral adapter contract, so you can run the same task through Claude and Codex and compare the resulting evaluation files directly — replacing 'I think this model is better' with a logged side-by-side. Dependency-ordered backlog execution that advances one verified task at a time, which means you avoid the common failure mode where an agent skips ahead and builds on work that never actually passed. MIT licensed and self-hostable with no API key required to run the replay demo, so you can validate the harness fits your workflow before wiring it to any external service.
Cons	Optimized primarily for Google Cloud deployment and Gemini models, though model-agnostic capabilities exist Development version builds directly from latest code commits may contain experimental changes or bugs not present in stable release	Orbit has no web UI and no managed control plane — non-engineers who need to review agent progress or trigger runs without touching a terminal cannot use it without a wrapper built on top, and building that wrapper puts the maintenance burden on your team. Task execution is sequential and single-agent per orbit: one task, one agent, one validation loop at a time. Teams that need agents running tasks in parallel — or coordinating across multiple agents on a shared codebase — hit this architectural ceiling immediately and move to a heavier orchestration framework. The adapter layer requires each coding agent to speak JSON over a CLI interface; agents without a scriptable CLI or JSON output format require a custom adapter, which the docs flag as a contribution opportunity but which in practice means engineering time before the harness is usable with those agents. There is no cloud execution or hosted option — everything runs locally or on infrastructure you manage. Teams under compliance requirements that mandate audit trails stored in a vendor-controlled environment, rather than self-managed storage, will need a different tool.

Bottom line

Agentmemory is open source; only Agent Development Kit (ADK) exposes a public API. Choose based on which difference matters most for your workflow.
