Cline Pricing Plans:

• Open Source (Individual): Free. Includes full extension functionality, BYOK, support for all AI models, and MCP server support. API costs are paid directly to providers.
• Open Source Teams: $20.00/month. Includes the first 10 seats free, centralized billing and team management, RBAC, JetBrains extension, and priority support. Per-user pricing applies after the first 10 seats.
• Enterprise: Custom pricing. Includes SSO (SAML/OIDC), SCIM provisioning, audit logs, private networking (VPC/private link), and self-hosted/on-prem deployments.

Devin Pricing Plans:

• Core: $20.00/month. Includes 9 ACUs per month, autonomous planning and execution, full shell, editor, and browser access, and collaborative pull requests. Additional ACUs cost $2.25 each (approximately 15 minutes of work per ACU).
• Teams: $500.00/month. Includes 250 ACUs per month, API access, team management, and priority support. Additional ACUs cost $2.00 each.
• Enterprise: Custom pricing. Includes custom ACU allocation, SaaS or VPC deployment, SSO and compliance, and dedicated support.

Pricing Analysis:

Both Cline and Devin offer a $20.00/month entry point for their paid tiers. However, Cline’s “Open Source Teams” plan at $20.00/month provides a fixed feature set with per-user pricing beyond the initial free seats, while Devin’s “Core” plan at the same price point is based on metered usage units (ACUs). This means that for consistent, high-volume usage, Devin’s cost can scale significantly beyond the initial $20.00, whereas Cline’s team plan is more predictable if exceeding the initial free seats. Cline also uniquely offers a completely free tier for individual users, making it more accessible for solo developers or those wanting to experiment without financial commitment.

Verdict

Cline and Devin represent distinct approaches to AI-assisted software development. Cline emphasizes an open-source, controllable, and adaptable platform with a strong focus on human oversight and customizability. Its unique features, such as BYOK and real-time cost tracking, cater to developers who prefer to maintain significant agency in their coding process and have transparency over AI operations and associated costs. Devin, on the other hand, aims to be a fully autonomous software engineer, capable of complex planning, multi-step execution, and integrating deeply into project workflows through features like collaborative pull requests and auto-generated documentation.

The absence of feature overlap means the choice is largely dictated by philosophical and functional preferences: whether to have a highly controllable agent that augments manual work (Cline), or a more hands-off, autonomous agent that takes on complete tasks (Devin). The pricing structures also present a divergence, with Cline offering a free individual tier and more predictable team pricing, while Devin’s metered ACU system may lead to variable costs for its core offering.
