Selecting an agentic platform requires looking past the low entry price-which averages just $32/month across public tiers-and analyzing where the free-to-paid trapdoors are hidden. In tools like Composio ($49/month), the primary upgrade trigger is integration depth and tool-calling frequency. If your agent only triggers once a day to draft an email, a free tier suffices. However, if you deploy browser-based automation agents like Bardeen, or complex multi-agent systems via Relevance AI, you will hit execution limits rapidly.
Before committing, map your expected monthly runs against the platform's execution limits. Only 8% of the market currently uses pure usage-based billing, meaning most tools force you onto higher flat-rate tiers long before you utilize their full feature sets. If you hit these limits, you can compare alternative platforms on our alternatives page to find more predictable cost structures.
For enterprise buyers, the decision hinges on execution environment. Self-hosted engines like n8n allow you to bypass cloud execution fees entirely by running workflows on your own infrastructure, whereas fully managed platforms charge a premium for hosting the agent's memory and state.
