Additional Considerations
Best Use Cases: Operations teams automating repetitive workflows without developer resources - lead qualification, email triage, meeting scheduling, CRM updates, customer support routing excel
Primary Strength: Zero-training deployment with Agent Builder ('vibe coding') creates sophisticated automations in 30 seconds vs 15-60 minutes with Zapier/Make for equivalent workflows
Unique Capabilities: Autopilot (Computer Use) enables automations impossible through traditional integrations - can interact with any web-based application without published APIs through AI-powered browser control
Multi-Agent Societies: Multiple specialized Lindies collaborate on complex tasks through delegation rules - Sales (SDR → AE → CS), Support (Triage → Technical → Escalation), Research with specialized investigators
Credit-Based Pricing Reality: Most common user complaint is unpredictable costs - 'credits consumed quickly and unpredictably' makes budget forecasting difficult vs fixed per-seat or usage-based pricing in competitors
Enterprise Limitations: Character limits (50M cap on Business tier) may constrain large deployments, US-only data residency blocks EU customers with strict localization requirements, no ISO 27001 certification may limit procurement
Developer Friction: Deliberately prioritizes no-code accessibility over developer tooling - NO public REST API, NO SDKs, NO CLI tools, NO programmatic RAG control makes it unsuitable for API-first use cases
Support Inconsistency: User reviews note 'inconsistent responsiveness on lower tiers' and 'writing to support twice with no response' - support quality varies significantly by plan tier
Platform Comparison Warning: Fundamentally different architecture from RAG-as-a-Service platforms - comparing Lindy to CustomGPT is misleading as they serve different product categories (workflow automation vs knowledge retrieval)
Limited UI customization: Limited ability to customize user interface and workflows to match specific brand requirements is primary user concern
Basic collaboration tools: Without real-time editing or advanced team management features can hinder team productivity when multiple people need to work together
No offline access: Guides unavailable without internet connectivity reducing usability in areas with unreliable internet
