OpenHands
Best when you want an open-source coding agent that can read codebases, write patches, run commands, and operate in a sandboxed environment.
Choose OpenHands if...
- coding agents
- PR generation
- codebase exploration
Not ideal if...
- teams that prefer IDE-integrated assistants
- non-engineering agent use cases
loop.js
loop.js is an open-source TypeScript framework for goal-driven agent loops. You declare a goal and verification bar; the engine runs Execute → Handoff → Verify rounds with fresh context each round, disk-backed memory, typed usd/rounds/timeout guards, crash-safe resume, and optional cron (local OS schedulers or Modal). The shipped executor uses Anthropic's Claude Agent SDK. Status is v0.2 beta (npm `@loop.js/core` 0.2.0-beta as of the July 2026 launch window).
Choose loop.js if...
- goal-driven loops with an independent Verify agent
- crash-safe, disk-backed rounds and typed spend/round guards
- scheduled maintenance loops via OS cron or Modal
- TypeScript teams already using Anthropic / Claude Agent SDK
Not ideal if...
- teams that need a multi-provider executor today (Claude Agent SDK only at v0.2)
- complex branching workflows better modeled as general graphs
- projects that cannot accept a pre-1.0 beta API surface
agentmaker
agentmaker is an open-source Python framework (pip package 0.2.0, Python 3.12+) that ships a unified agent loop for chat, ReAct, plan-and-solve, and reflection, plus built-in hybrid retrieval, Mem0-style long-term memory, RAG, MCP tool loading, guardrails, human-in-the-loop approve/resume, run limits, and tracing to JSONL, SQLite, or OpenTelemetry—with local SQLite defaults and swappable backends.
Choose agentmaker if...
- single-import Python agent stacks
- local-first hybrid retrieval and memory
- MCP tool integration with guardrails and HITL
- teams that want swappable SQLite-default backends
Not ideal if...
- TypeScript-first teams
- teams that need a large battle-tested graph orchestration ecosystem
- products that only need a thin typed agent wrapper without retrieval or memory
What to consider
- Does the alternative solve the same agent layer, or is it a lower-level building block?
- Will switching improve observability, permission boundaries, state control, or evaluation coverage?
- Can the team validate the migration with one real agent task before replacing the current tool?
