Dropstone vs Relay.app Agents: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Dropstone and Relay.app Agents — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
Dropstone
Blankline
Self-hosted AI agent with long-term memory that spans CLI, chat, SDK and real-world actions, running on open-weight models you host.
Key features
- Persistent Cross-Surface Memory: Teach the agent something once in the CLI and it already knows it in chat, in the SDK and on a phone call — memory persists per user across sessions and surfaces instead of dying with one login.
- Self-Hosted Open-Weight Stack: Run the entire agent inside your own walls on your keys, machines and network, using open weights the company hosts or local models through Ollama, so source code never leaves your infrastructure.
- Proactive Background Operation: The agent is already running rather than waiting to be opened — it monitors what you asked it to watch and hands back only the decision that was actually yours.
- Approval-Gated Real-World Actions: Control smart-home devices, monitor an inbox around the clock, place phone calls and look up half-remembered contacts, with every action gated behind an explicit approval.
- 1M-Token Context on Every Tier: A one-million-token context window is included even on the free plan, letting the agent hold an entire repository in mind at once.
- Model-Agnostic Tiering: Dropstone Fast, Pro and Heavy each run whatever tops the open-weight leaderboards that month rather than being tied to a single lab.
- Learned Skills: The agent picks up skills it does not yet have, retains them and reuses them without being asked twice, with the skill list growing month over month.
- Multi-Surface Access: Reach the same agent through the Dropstone CLI, a web dashboard, VS Code / Cursor / Windsurf extensions and Remote MCP connectors, with sandboxed code execution and plan mode before changes apply.
Best for
- Air-Gapped Engineering Teams: Ship real code with an AI agent while keeping the models, the repository and the network entirely inside company infrastructure.
- Always-On Inbox Triage: Let the agent watch an inbox around the clock and surface or act on the messages that matter instead of checking it yourself.
- Terminal-Native Development: Use the CLI agent to generate code, run it in a sandbox and open diffs, with plan mode and approval gates before anything is applied.
- Personal Operations Automation: Hand off recurring real-world tasks — smart-home control, placing a call, chasing a contact — to an agent that already has your context.
- Cost-Sensitive Heavy Usage: Get several times more weekly coding usage per dollar than subscription coding CLIs by running on self-hosted open-weight models.
- Custom Agent Integration: Embed the same memory-backed agent into your own stack through the SDK and Remote MCP connectors.
Relay.app Agents
Relay (relay.app)
No-code platform to build and run autonomous AI agents that automate tasks across Gmail, Notion, HubSpot and hundreds of other apps.
Key features
- No-Code Workflow Builder: Drag-and-drop interface and pre-built templates let non-technical users design multi-step agent workflows without writing code, speeding deployment of automation.
- Multi-App Integrations: Native connectors and integration support for hundreds of apps (explicitly including Gmail, Notion, HubSpot) to read, write, and synchronize data across systems.
- Proactive Background Agents: Agents can run continuously or on schedules to monitor inboxes, databases, or other sources and take actions autonomously day and night.
- LLM Backend Support: Integrations with large language models such as GPT-4 and Claude (reported in third-party sources) to enable natural language understanding, generation, and complex decision logic within agents.
- Human-in-the-Loop Controls: Options to pause workflows for human review, approve outputs, or intervene in agent decisions to maintain quality and compliance.
- Templates for Common Tasks: Ready-made templates for use cases like lead enrichment and customer support that reduce setup time and provide best-practice starting points.
- Drag-and-drop no-code workflow and agent builder
- Pre-built templates for common automations (e.g., lead enrichment, support)
- Integrations with Gmail, Notion, HubSpot and hundreds of other apps
- LLM integrations (reported GPT-4 and Claude support)
- Human-in-the-loop controls for oversight and handoffs
- Proactive agents that operate 24/7 and improve over time
- Tiered pricing with free tier and paid plans
Best for
- Lead Enrichment: Automatically gather and append contact data from email threads, public sources, and CRMs into HubSpot or other CRM records to speed sales outreach.
- Customer Support Triage: Monitor incoming support emails or tickets (Gmail/Helpdesk), categorize and prioritize them, and either auto-respond or escalate to human agents with context.
- Automated Knowledge Ops: Create and maintain Notion pages by extracting insights from meeting notes, emails, and documents, keeping internal knowledge bases up to date.
- Email Automation and Summarization: Continuously monitor Gmail, summarize long threads, and generate suggested replies or follow-up actions for faster inbox management.
- Cross-System Orchestration: Detect events in one app (e.g., form submission) and trigger multi-step workflows across several apps (CRM updates, Slack alerts, task creation) without custom engineering.
- Monitoring & Alerting: Run agents that watch for KPI changes, exceptions, or deadlines and notify stakeholders or kick off remediation workflows automatically.
- Lead enrichment and sales engagement automation
- Customer support ticket triage and response automation
- Automating routine operational tasks across SaaS apps
- Content generation and data extraction workflows
- Integrating LLM-driven agents into existing CRM and productivity stacks
