# What are the cheapest AI agent builder tools that still have solid integrations with Slack and HubSpot?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">I’ve been looking into the cheapest <a class="a a--md" elv="true" href="https://www.g2.com/categories/ai-agent-builders">AI agent builder tools</a> that still have solid integrations with Slack and HubSpot, and the trade-off here feels pretty real. A lot of lower-cost tools make it easy to get started, but once you need reliable integrations across communication and CRM systems, things can get inconsistent.</p><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">From what I’ve seen so far, Zapier, Workato, Lindy, and CloseBot seem to balance cost and integration capability reasonably well.</p><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">Here are the ones that might be worth exploring:</p><ul>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/zapier/reviews">Zapier</a> (4.5/5, 1,958 reviews): Probably the most straightforward option for connecting Slack, HubSpot, and a wide range of other tools. It’s relatively affordable, though more complex workflows can quickly increase costs.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/workato/reviews">Workato</a> (4.7/5, 752 reviews): Known for strong integration depth, especially in more structured workflows. It’s powerful for connecting systems like HubSpot and Slack, but may not always fall into the “cheap” category depending on usage.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/lindy-lindy/reviews">Lindy</a> (4.9/5, 170 reviews): Feels like a more lightweight, flexible option for building agents that can plug into different tools. It’s easier to experiment with, though integration reliability at scale is still something I’m trying to understand.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/closebot/reviews">CloseBot</a> (4.8/5, 124 reviews): More focused on conversational use cases, but can integrate with communication tools for support or engagement flows. It’s simpler, though less robust for broader workflow automation.</li>
</ul><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">What I’m still trying to figure out is where the real cost shows up. Is it better to start with a cheaper, flexible tool and layer integrations over time, or do teams end up spending more fixing limitations compared to starting with a more robust platform?</p>
