Hotglue provides an embedded integration platform as a service (iPaaS) that allows SaaS companies to integrate customer-facing features and automate workflows, offering three pricing plans: Basic, Pro, and Enterprise. Each plan provides various levels of support and access to features like API connectors and a Python transformation layer, with more advanced features available in higher-tier plans. However, some drawbacks include a lack of specific pricing details and the necessity to consult with sales representatives for more information, as well as limited support details in the Basic and Pro plans. In contrast, Merge offers a unified API solution with a free plan that allows users to test integrations without sales interactions and provides more transparent support across its pricing tiers, including integration observability features and a shared Slack channel for professional support, making it a competitive alternative for building reliable and secure integrations.
