Tools like Plain and Intercom make these automations accessible through well-documented APIs.
What should I look for in a support tool for a SaaS product?
Prioritize tools with: API-first design for custom integrations, in-app messaging and live chat, ticket management with automation rules, self-service knowledge base, integration with your CRM and engineering tools (Linear, Jira), and usage analytics. Plain and Intercom excel for B2B SaaS, while Freshdesk offers the best value with its free tier.
