Best for the job10 picks · updated Oct 10, 2026
For a general agent that researches and builds websites and slides on its own computer, pick Manus from $20 a month. For coding, pick OpenAI Codex (from $8 a month with ChatGPT Go) or Claude Code (from $20 with Claude Pro). For agents inside business workflows, pick n8n or Make. 6 of the 10 picks have a free plan.
AI agents fall into three groups. General agents (Manus, Ottermind) take a goal and produce research, slides or sites. Coding agents (OpenAI Codex, Claude Code, Factory) edit files and run commands. Workflow tools (n8n, Make, Innflow) chain agent steps with your apps. Nearly all bill by credits, executions or plan limits, so one complex task can use a large share of the monthly allowance. Claude Code, Factory, AllyHub and Marblism have no free plan.

It depends on the job. In our list, Manus is the pick for general multi-step tasks, OpenAI Codex and Claude Code for coding, and n8n or Make for automated workflows.
AI agents are tools that plan and carry out multi-step tasks instead of only answering in chat. For example, Manus plans and executes tasks in its own sandboxed computer, and Claude Code reads your codebase, edits files and runs commands.
For building your own agents, n8n suits technical teams and can be cloud-hosted or self-hosted, while Make is a visual no-code platform that connects thousands of apps. Innflow combines agents and workflows for small teams.
Make lets you build AI agents in a visual no-code editor, and AllyHub offers no-code agents that collect and monitor web data. Technical teams that want more control can use n8n.
Our 10 picks are Manus, OpenAI Codex, Claude Code, n8n, Make, Factory, Ottermind, Innflow, AllyHub and Marblism. Three are coding agents (OpenAI Codex, Claude Code, Factory), and n8n, Make and Innflow are workflow platforms.
Manus, OpenAI Codex, n8n, Make, Ottermind and Innflow list a free plan in our data. Claude Code starts at $20/month (Pro), and Factory also starts at $20/month (Pro).
