Competitive Landscape

Who Keystroke competes with, and how they differ.

M

Mastra

The closest shape match: an open-source TypeScript framework (Apache 2.0, from the Gatsby team) bundling agents, typed workflows, memory and evals, with Mastra Cloud or self-hosting for deployment and tracing. Mastra sells the framework and a developer-facing control plane; Keystroke pairs its TypeScript SDK with a managed end-user web app where non-engineers run the agents, which Mastra leaves to the customer to build.

Gumloop7.1/10

Named by Keystroke's founders as the visual-builder side of the market they position against. Gumloop is a drag-and-drop canvas for team automations with IT-controlled access, so business users ship without engineering; Keystroke inverts that — agents are authored as TypeScript in the customer's own repo with Zod schemas and Vitest tests, then surface in a shared web app.

n8n8.1/10

The other founder-named contrast, and the default incumbent for this budget: source-available, self-hostable visual workflow automation with AI agent nodes and a very large integration library. n8n is node-graph-first with code as an escape hatch and is widely deployed on-prem; Keystroke is code-first with the graph as a rendered view, and is sold as a managed runtime rather than a self-hosted server.

Dust7.4/10

Also an internal-agent platform sold to whole teams, but built around connected company knowledge — Slack, Notion, Drive and ~60 other sources — with no-code agent creation and Slack as the main surface. Keystroke competes on the build side instead: a sandboxed VM with file system and code execution, a browser that stays signed in, durable long-running execution and human approval gates, none of which Dust targets.

Relevance AI7.2/10

Sells the same outcome — custom agents doing internal work — through a no-code builder and an "AI workforce" framing aimed at sales and ops teams rather than engineers. Overlaps Keystroke on multi-agent delegation and tool/integration breadth, but has no repo-based authoring, test-suite gate or code-execution workspace.

CrewAI7.7/10

The code-first alternative for teams that pick Python: an open-source multi-agent framework organised around role-based crews, plus an enterprise control plane for deploying and monitoring them. Genuine overlap on multi-agent orchestration and production observability; it splits from Keystroke on language (Python vs TypeScript) and on the missing managed app that lets non-technical colleagues actually use the agents.
