# How does Cosine compare to alternatives?

**Cosine is the only AI engineering platform built for autonomous, end-to-end task completion — not just code suggestions.** While copilots and developer assistants help with line-by-line generation, Cosine delivers full pull requests that are planned, validated, and ready for review.

### Cosine vs. Devin-style agents

| Feature                  | **Cosine**                                                              | **Devin-style agents**                |
| ------------------------ | ----------------------------------------------------------------------- | ------------------------------------- |
| **Workflow**             | Asynchronous, runs in the background; integrates with Jira/GitHub/Slack | Interactive, single-threaded sessions |
| **Security**             | Cloud, VPC, or fully on-prem (air-gapped)                               | Cloud-only, often hosted LLM APIs     |
| **Scalability**          | Multi-agent orchestration and PR-based output                           | Limited concurrency                   |
| **Enterprise readiness** | SOC 2 / ISO-aligned, deployable in restricted environments              | Early-stage or hosted only            |

Cosine focuses on enterprise-grade reliability and compliance — suitable for banks, defense, and large-scale engineering teams.

### Cosine vs. Cursor and Windsurf (IDE copilots)

| Feature               | **Cosine**                               | **Cursor / Windsurf**                           |
| --------------------- | ---------------------------------------- | ----------------------------------------------- |
| **Placement**         | Web + integrations (Jira, GitHub, Slack) | In-IDE extensions                               |
| **Scope**             | Autonomous multi-task agent              | Inline code completion and refactor suggestions |
| **Team productivity** | Handles dozens of tickets in parallel    | Speeds up individuals only                      |
| **Deployment**        | Cloud, VPC, on-prem                      | Local or cloud plugin                           |
| **Data security**     | No external egress; private model use    | May send snippets to external APIs              |

Cosine complements rather than replaces IDE copilots. Many teams use both: copilots for **micro-level speed**, Cosine for **macro-level delivery**.

### Cosine vs. GitHub Copilot / Codeium

| Feature               | **Cosine**                                  | **Copilot / Codeium**              |
| --------------------- | ------------------------------------------- | ---------------------------------- |
| **Mode**              | Autonomous agent                            | IDE assistant                      |
| **Output**            | Full pull requests with validation          | Inline suggestions                 |
| **Context awareness** | Reads and reasons across entire repos       | Limited to open files              |
| **Data control**      | Private, non-training environment           | Cloud-based, shared model training |
| **Use cases**         | Backlog cleanup, bugfixes, migrations, docs | Individual coding acceleration     |

### Why teams choose Cosine

* **Scale:** Parallel task handling across projects.
* **Security:** Fully deployable within private infrastructure.
* **Depth:** Understands and modifies large, unfamiliar codebases.
* **Autonomy:** Requires no real-time human supervision.

Cosine is the only option purpose-built for **real engineering environments**, where compliance, quality, and throughput matter as much as speed.
