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

Model-agnostic AI coworker for Slack and Microsoft Teams that routes each task to the best of 80+ models and returns the work in-thread.

Model-Agnostic Routing: Routes each tagged task through Conifer to the best of 80+ models across Claude, GPT, Gemini, Grok, DeepSeek, Qwen and more, cutting model spend by around 70%.
Lives in Slack and Teams: Works where the team already collaborates, so results come back in the same thread the request started in with no separate app to open.
Sandboxed Cloud Runs: Every run executes on its own cloud machine, scoped to connected tools and torn down on completion.
Self-Proposing Automations: When the same request repeats three times, OpenTag offers to own it on a schedule, and you approve once instead of configuring a workflow.
Self-Organizing Wiki: Writes and revises pages out of how the company actually operates, sourced to the originating threads, and notes what changed when a decision moves.
Per-Person Permissions: Everyone in a channel works with the same OpenTag, but access follows the individual who asked and invite-only channels stay private.
Connector Integrations: Works with HubSpot, Gmail, GitHub, Stripe, Zendesk, Notion, PostHog and your own database.
Human Sign-Off Gate: Holds any output that would leave the company until a person approves it, and posts finished work with the steps behind it.

Recurring Team Reports: Have the Monday metrics pulled, written and posted to a channel every week without anyone re-asking.
Invoice and Collections Chasing: Schedule a weekly invoice chase across Stripe and email, with anything customer-facing held for approval.
Institutional Knowledge Capture: Keep pricing, refund policy, customer tiers and runbooks current as decisions change in channels.
Cross-Tool Analysis: Audit CAC by campaign or similar questions that span HubSpot, Stripe, PostHog and an internal database.
Support and Ops Triage: Answer routine questions from company context in-thread so teammates stop interrupting each other.
Cost-Controlled AI Access: Give a whole workspace AI help on a shared credit pool instead of buying per-seat frontier-model licenses.
