Open-source coding agent runtime that runs in your IDE, your terminal or embedded via SDK, works with any model, and asks approval on every step.

One runtime, three surfaces: The same agent runs as a VS Code extension, a terminal CLI, or embedded in your own product through the SDK
Model agnostic: Works with Claude, GPT, Gemini, local Ollama or LM Studio models and any OpenAI-compatible endpoint, using your own key or weights
Plan then Act: Align on a strategy in Plan mode before execution, then approve each step in Act mode or flip on auto-approve
Multi-file edits with undo: Coordinated changes across a project with linter-aware fixes, diffs, checkpoints and one-click undo on every step
Live terminal execution: Runs bash commands and reacts to output as it appears, handling dev servers, test runs and deploys
Rules and Skills: Ship .clinerules with the repo so the agent follows your coding standards, architecture and deployment conventions
Multi-agent teams: Coordinator agents delegate to specialists with their own tools and context, and can run on cron for recurring automation
MCP and integrations: Register MCP servers and custom tools, chat from Slack, Discord, Telegram or Linear, and run headlessly in GitHub Actions or GitLab

A developer onboarding to an unfamiliar codebase and asking the agent how files, dependencies and behaviour fit together
Refactoring across a large repository while keeping imports, types and behaviour consistent
Running recurring maintenance — dependency bumps, lint sweeps, scheduled checks — from cron or a CI pipeline
A team that must keep code on self-hosted or local models for compliance reasons, pointing the agent at its own endpoint
Embedding an agent loop inside an internal developer platform via the SDK instead of building one from scratch
Encoding team conventions in .clinerules so every engineer's agent produces consistent, review-ready changes
Triggering a coding task from Slack or Linear and having the agent open the resulting change

Product adoption agent that reads each user's in-product behavior and writes timely, personalized guidance to move them to the next feature or habit.

Adoption Goal Campaigns: You define the product behavior you want users to adopt and Lumi builds the campaign around it, qualifying an audience and giving a clear reason for every match.
Behavior-Grounded Personalization: Lumi reads each user's actual session history and writes a message specific to what they did, rather than merging variables into a shared template.
Actionable Plan Delivery: Every nudge hands the user's own stalled task back to them as a short runnable plan with a single call to action, instead of a generic feature announcement.
Brief-Based Guardrails: You set goal, context, tone and guardrails once - quiet hours, one nudge per N days, skip conditions - and Lumi writes every message inside those limits.
Dual Data Sources: Lumi combines your product database, which shows what each customer is entitled to do, with your analytics, which shows what they actually do, to pick the next best action.
Behavioral Outcome Measurement: Success is tracked against product KPIs such as feature adopters and usage quality rather than email opens or clicks, showing who adopted and who stalled.
PostHog and Database Integrations: Native PostHog and database integrations are available from the free tier upward, with additional data integrations on higher plans.
Ship-Speed Follow-Up: As the product changes, Lumi continuously finds the users who have fallen behind on new functionality and gives each the guidance to catch up.

Feature Launch Adoption: After shipping a new feature, automatically identifying which existing users it applies to and explaining it to each of them in their own context.
PLG Activation: Moving self-serve signups past their first stalled workflow so trials convert without a human onboarding call.
Scaled Customer Education: Giving every account the founder-level attention that was only feasible for the first ten customers, across thousands of users.
Churn Risk Intervention: Catching users who repeatedly retry, abandon or work around a task and sending them a corrective plan before frustration turns into churn.
Habit Formation: Nudging power users toward higher-leverage workflows such as planning before execution, and measuring whether the habit actually took.
Adoption Reporting: Showing product and growth teams which KPIs moved after guidance went out, tied to specific campaigns.
