Dropstone vs Rosply: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of Dropstone and Rosply — 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.
Rosply
Rosply
Rosply is an AI desktop agent that automates repetitive Windows tasks by viewing the screen and controlling mouse and keyboard like a human.
Key features
- Vision-Based Control: Takes a screenshot every step and reads dialogs, popups, and dynamic UI like a human, with no DOM scraping or XPath required.
- Cross-Application Automation: Controls Chrome, Excel, VS Code, and legacy enterprise software—anything that runs on the desktop—without plugins.
- Instant Halt Control: Press Ctrl+H at any moment to immediately stop the agent, or close the terminal window for a clean exit.
- Multi-Platform Support: Fully tested on Windows 10/11, supported on Linux, and functional in beta on macOS, with mouse, keyboard, and screenshot control on all.
- Model-Agnostic via OpenRouter: Sends only screenshots and task text to OpenRouter, letting you pick the underlying AI model.
Best for
- Repetitive Data Entry: Automating form-filling and data transfer across desktop apps without scripting.
- Legacy Software Operation: Driving old enterprise tools that lack APIs by interacting through the visible UI.
- Spreadsheet Workflows: Performing multi-step Excel tasks autonomously from a plain-text instruction.
- Browser Automation: Navigating and completing tasks in Chrome the way a person would.
