Our take: Choose Dropstone if you want a terminal-first coding agent with one memory shared across CLI, chat and editor extensions, starting free and moving to Pro at $15 per month for the Heavy model tier.
Main limitation: Free usage is limited monthly, and consumer plans have session-content programs for training Dropstone's own models switched on by default.
Who Dropstone fits
Choose Dropstone if you want a terminal-first coding agent with one memory shared across CLI, chat and editor extensions, starting free and moving to Pro at $15 per month for the Heavy model tier. Based on the vendor's documentation, not on a hands-on test.
Best for: Developers wanting a terminal-first coding agent
Also a good fit for
- Teams preferring open-weight models with no data retention
- Users who want one agent across CLI, chat and editor
Consider another tool if free plan has limited monthly usage
Or if
- Heavy model tier only on Pro and above
- Phone-call actions restricted to Max plan

What is Dropstone, and how does it work?
Dropstone is a coding agent from the research lab Blankline that keeps one memory per account across its CLI, web chat, SDK and VS Code/Cursor/Windsurf extension. It offers Fast, Pro and Heavy model tiers built on open-weight models, a 1M-token context window on every tier, plan mode, sandboxed code execution and approval gates on tool calls. Beyond code, the agent can watch an inbox, control smart-home devices and place phone calls (Max plan). Managed inference is US-hosted with zero data retention. The CLI installs as a single binary on macOS, Windows and Linux; a Free plan has limited monthly usage, and Pro/Max plans raise limits and add the Heavy tier and priority routing.

- Download the single-binary CLI from the downloads page for macOS, Windows or Linux (or add the VS Code, Cursor or Windsurf extension)
- Sign in from the CLI and pick Dropstone Fast, Pro or Heavy as the model
- Optionally add an AGENTS.md with project conventions and connect tools via Remote MCP
Example: fixing a bug in a repository with a terminal coding agent
- Open a terminal in the repo and start the CLI
- Describe the bug and switch on plan mode so the agent proposes changes first
- Approve the proposed edits and the approval gate on each tool call
- Let it run tests in the sandbox and review the resulting diff
Review and export the result
- Review the diff before accepting and run your own test suite
- Check the usage page in the dashboard for what the request consumed

How your inputs and outputs are handled
Only relevant code snippets are sent to inference endpoints; indexing and embeddings run locally.
Policy says no third-party training and stateless inference, but Free, Pro and Max accounts are opted by default into programs using outcome metadata and full coding sessions to post-train Dropstone's own models; can be turned off in dashboard settings; Enterprise excluded.
Inference is ephemeral; derived memory (knowledge, lessons, summaries) is retained against your account.
Commercial use and plan restrictions
