Frequently Asked Questions
What is the best free knowledge base software?
Freshdesk offers a generous free tier for knowledge base software. However, free plans often have limitations. Converge at $49/mo flat for up to 15 agents offers better value for growing teams.
Are free knowledge base software options good enough?
Free options work well for very small teams or testing. But they often limit agents, features, or channels. If you need multi-channel support, team collaboration, or professional features, consider Converge's $49/mo flat plan.
What are the limitations of free knowledge base software?
Common limitations include: 1-2 agents only, limited channels, no automation, branding on widgets, no analytics, and slow support. Paid plans like Converge ($49/mo for 15 agents) remove these restrictions.
When should I upgrade from free to paid knowledge base software?
Upgrade when you need: more than 1-2 agents, multiple channels (WhatsApp, Telegram, etc.), advanced features, or better support. Converge offers flat $49/mo pricing that doesn't penalize team growth.
Is Converge free?
Converge offers a 14-day free trial, then costs $49/month flat for up to 15 agents. Unlike per-seat pricing, your cost stays the same as your team grows—making it more affordable than most "free" options at scale.
