# Backlog > Backlog is a product development workspace for teams and agents. It combines tasks, projects, roadmap views, activity history, teams, and automation in one shared model. Use this file as the main entry point for agents and LLMs. Follow the linked section-level `llms.txt` routes for discovery. Use the linked `/README.md` docs pages for exact page content, and `/llms-full.txt` only when you need the full public docs corpus in one file. ## Product model - Tasks are the main execution object in Backlog. - Projects hold planning context, milestones, updates, and derived health. - Roadmap views are derived from live project dates and milestone markers. - Teams and member profiles shape ownership, visibility, and access. - Drafts, inbox, and search support review, follow-up, and navigation work. - Workspace automations and visible agents are separate objects and should not be treated as interchangeable. - Human sessions, personal access tokens, and shared automation credentials are different access lanes. ## Choose documentation by surface - [Docs index](https://backlog.to/docs/llms.txt): Main documentation index. Covers 3 interfaces, 28 topics, and 90 guides. - [Web](https://backlog.to/docs/web/llms.txt): Sign in, work in the browser, and run your workspace from the Backlog web app. Covers 13 topics and 42 guides. - [API](https://backlog.to/docs/api/llms.txt): Authenticate clients, inspect workspace context, and automate work safely over the Backlog API. Covers 7 topics and 22 guides. - [CLI](https://backlog.to/docs/cli/llms.txt): Download the Backlog CLI, authenticate, inspect context, and run terminal-first workflows. Covers 8 topics and 26 guides. ## Access model - Human sign-in starts with the shared OTP flow documented in the auth guides. - Browser work happens in the web workspace and its settings surfaces. - Programmatic work happens over REST or the CLI after the correct auth lane is established. - Shared automation access is workspace-scoped and separate from human-owned personal access tokens. ## Public product pages - [Product](https://backlog.to/product): High-level product overview for how Backlog keeps product teams aligned from strategy to shipping. - [Pricing](https://backlog.to/pricing): Commercial pricing based on monthly created-task volume. Paid plans stay feature-complete. - [Changelog](https://backlog.to/changelog): Public release and improvement feed. - [About](https://backlog.to/about): Company-level context about Backlog. - [Privacy](https://backlog.to/privacy): Public privacy page. - [Terms](https://backlog.to/terms): Public terms of service page. - [Sign in](https://backlog.to/auth/signin): Browser sign-in entry point for existing users. - [Sign up](https://backlog.to/auth/signup): Browser sign-up entry point for new users. ## Machine-readable resources - [Full documentation corpus](https://backlog.to/llms-full.txt): One plaintext file with the entire public docs corpus. - [Docs sitemap](https://backlog.to/docs/sitemap.xml): Public docs URL inventory. Useful for discovery, not as the curated entry point.
