How to choose AI Agent Platforms tools
AI Agent Deployment is the most common job here, but tools also cover workflow automation, monitoring running agents, and building autonomous agents from the ground up. Where they differ most is how much you need to code, what they cost before anything runs, and how much of the work they hand back to you.
Diagrid is the only tool here that shows both a free tier and clear paid prices, starting at $1,199 a month for a dedicated cloud plan. Gumloop has a free plan and a Pro at $37 a month, covering AI Agent Deployment, monitoring, and workflow building without code. Floatboat is freemium and triggers work from calendar events rather than manual prompts. WorksBuddy and Auto-GPT cost nothing at all. Most other tools here, including Claude Platform, Kimi, and 3CLogic, give no price without a sales call.
How much you need to code
Gumloop lets you build and deploy agents without writing code, and its free plan lets you start before spending anything. Floatboat works the same way, automating tasks from calendar events through a no-code setup. Diagrid sits at the other end: it supports multiple agent frameworks and handles crash recovery and verifiable execution, but self-hosted deployments require familiarity with distributed systems and container orchestration tools. Pi is the most technical tool here, a terminal coding agent that requires command-line knowledge and TypeScript for extensions, with no hosted service at all. Claude Platform is built for developers and offers APIs across multiple programming languages.
What the platform costs before your first agent runs
WorksBuddy and Auto-GPT are completely free. Gumloop and Diagrid both have free tiers, so you can test them before paying. Floatboat's free plan costs nothing monthly, with a one-time $12.99 booster pack if you need more credits. Leapd starts at $39 a month. AppZen, 3CLogic, Kimi, and Claude Platform all require a sales call before you see a number. Diagrid's Dedicated Cloud plan is $1,199 a month. Its Bring Your Own Cloud option is $1,599 a month, which makes it the clearest but also the most expensive of the tools that publish prices.
Whether the platform watches agents after they run
Deploying an agent and keeping it running reliably are different problems. Diagrid handles both. It automatically recovers from crashes and outages so no progress is lost. It also produces a cryptographic record of every execution so teams can verify what ran and when. Gumloop covers monitoring alongside deployment and includes role-based access control and audit logs for teams that need them. Claude Platform also covers monitoring for agents built on its infrastructure. Most other tools here focus on building and launching agents but publish nothing about what happens when an agent fails mid-task.
6 questions
Frequently asked questions
Which AI agent platforms are free to use?
WorksBuddy and Auto-GPT are completely free. Gumloop and Diagrid both have free tiers you can start on without a credit card. Floatboat is freemium with a free monthly plan and a one-time $12.99 booster if you need extra credits. Every other tool here is paid only, and most require a sales call before they share a price.
Which platform suits deploying agents without writing code?
Gumloop is the clearest option for that. It has a no-code agent builder, supports multi-agent workflow orchestration, and its free plan lets you start without paying. Floatboat is also no-code and automates work triggered by calendar events. Both are accessible without a technical background, unlike Pi or Diagrid, which require command-line or distributed-systems knowledge.
Which tools publish their pricing openly?
Diagrid, Gumloop, Floatboat, Leapd, and REVE Chat all publish at least some prices. Diagrid's Dedicated Cloud is $1,199 a month and its Bring Your Own Cloud is $1,599 a month. Gumloop's Pro is $37 a month. Leapd starts at $39 a month. Floatboat's booster pack is a one-time $12.99. AppZen, 3CLogic, Kimi, and Claude Platform give no price without contacting sales.
Which platform handles agent failures and keeps a record of what ran?
Diagrid is built specifically for this. It automatically recovers from crashes so agents pick up where they left off. It also produces a cryptographically verifiable record of every execution so teams can check what ran for audit and regulatory purposes. Gumloop also keeps audit logs and supports role-based access control, but its focus is on building and running workflows rather than durable execution guarantees.
Can I use any of these platforms for customer support automation?
REVE Chat is the tool here built for that job. It combines live chat, chatbots, and AI agents in a single inbox, with multilingual support and multi-intent detection. Its paid plans start at $14.99 a month. 3CLogic covers voice-based customer interactions and integrates with CRM systems, but gives no price without a sales call. Neither is a general-purpose agent platform.
Which tools suit a developer building agents from scratch?
Claude Platform and Pi are both aimed at developers. Claude Platform provides APIs across multiple programming languages, with token-based pricing and volume discounts available. Pi is a terminal coding agent you install yourself, with no hosted service and no published price. Diagrid also targets developers who need reliable, recoverable execution for distributed agent systems, with a free cloud tier to start on.
