Exponential
The next generation dev platform for teams. Issues, customer feedback, and coding agents in one realtime tracker. Agents run on your own machines, on your own subscription. Web, macOS, Linux, Windows, iOS, Android.
What you get
- Issues with statuses, priorities, labels, estimates, due dates, sub-issues and relations, markdown, @mentions and #issue references, full-text search, drafts that follow you across devices. Realtime sync on every client via ElectricSQL. Moving from Linear? Settings → Import brings your issues over.
- Boards backed by a GitHub repo: a session's branch and PR are tracked on every issue it works; several issues started together share one branch and one PR. The PR opening moves the issue to In Review, the merge to Done.
- Start: hand an issue to Claude Code or Codex from any client, on any of your machines. It codes in a worktree and opens the PR.
- Chats: one chat per piece of work, with its conversation, its issues, every session it runs and a Guide to the PR. Watch the transcript, answer the agent's questions and approve its plans, read the diff and the screenshots it publishes, from your phone or the desktop.
- Your machines, your logins: every desktop and server lists its agent accounts with plan, usage and reset times; switch a session to another account when one hits its limit.
- Prompts and agents: saved team prompts run from the composer's
/ menu; team agents wake on a schedule or an issue event and run on your own machines.
- Apps: describe a dashboard or a checklist and an agent session builds it as a team app, with a live preview and versions. Apps keep their own records, read the team's boards, issues and chats, act as you through the tools an owner grants, and travel as one file.
- Headless CLI:
exponential turns any Linux or macOS box into an always-on agent machine your team starts sessions on.
- Feedback widget: a script tag for your site; reports with annotated screenshots land as issues, and the reporter keeps a conversation with your team through an emailed link.
- MCP server at
/api/mcp (16 tools) for Claude Code, Codex, ChatGPT, Cursor, or any MCP client.
Self-host
mkdir exponential && cd exponential
curl -fsSLO https://raw.githubusercontent.com/Niach/exponential/master/selfhost/docker-compose.yaml
curl -fsSL https://raw.githubusercontent.com/Niach/exponential/master/selfhost/.env.example -o .env
# fill in .env: two secrets + S3 credentials
docker compose up -d
App at http://localhost. Migrations run on boot. A GitHub App is only needed for the coding features. Full runbook: INSTALL.md, env reference: .env.example. Upgrade with docker compose pull && docker compose up -d.
The only cloud-only feature is mobile push (store apps are built against the first-party Firebase project).

Development
Needs bun, Node ≥ 22.12, and Docker Compose.
bun install
cp .env.example .env
cp Caddyfile.example Caddyfile
bun run backend # docker compose up -d + web dev server (localhost:3000)
bun run storage:init # one-time S3 bootstrap, prints keys for .env
apps/web TanStack Start app: tracker, API, Electric shape proxies
apps/desktop Rust IDE (gpui)
apps/ios SwiftUI
apps/android Kotlin / Compose
apps/marketing exponential.at
packages/ db schema, widget, icons, contracts
Other scripts: bun run ios, bun run android, bun run dev:desktop, bun run typecheck, bun run test. Don't run bun run lint (its --fix breaks typeof import() sites). Architecture notes live in CLAUDE.md.
