Evidence-backed decision brief

Which AI coding agent fits a 20-person engineering team?

Compare Aider, Amazon Q Developer, Devin, and Gemini Code Assist across the product facts, enterprise controls, data policy, integrations, and execution evidence that can change a team decision.

Decision context · Engineering leaders evaluating team-wide adoption
Candidate inclusion rule

Included when the product is a maintained coding Agent with public first-party documentation for repository work and enough evidence to assess the listed decision requirements. The current cohort is Aider and Amazon Q Developer and Devin and Gemini Code Assist; inclusion is not a ranking or claim that no other product qualifies.

Pricing

Aider documents that model access is configured through external providers or API keys, so the selected model provider determines the usage cost structure.

Source-Backed

Amazon Q Developer publishes a Free tier and a Pro tier priced per user per month, with different agentic-request and transformation allowances.

Source-Backed

Devin publishes Free, Pro, Max, and Teams plans with documented member and usage rules.

Source-Backed

Gemini Code Assist publishes Standard and Enterprise licenses with monthly and 12-month commitment prices and plan-specific feature differences.

Source-Backed
Deployment

Aider installs into a local Python environment and runs from the terminal against a local codebase, with an optional Docker installation path.

Source-Backed

Amazon Q Developer is installed as an extension or plugin in supported Eclipse, JetBrains, Visual Studio Code, and Windows Visual Studio environments, with Builder ID or IAM Identity Center authentication depending on the tier.

Source-Backed

Devin Enterprise documents managed environment options and their administration model.

Source-Backed

Gemini Code Assist is available directly in Cloud Shell, Cloud Workstations, and Android Studio and through extensions in VS Code and supported JetBrains IDEs; it also supports documented command-line and infrastructure interfaces.

Source-Backed
Capabilities

Aider is a terminal-based AI pair programmer that edits local Git repositories, supports multiple models and modes, and can run tests and linting.

Source-Backed

Amazon Q Developer documents IDE chat, agentic coding, inline suggestions, workspace context, transformations, security scanning, and code optimization or refactoring across supported IDEs.

Source-Backed

Devin Review supports documented pull-request analysis, review, security scanning, and code-change workflows.

Source-Backed

Gemini Code Assist documents IDE code completion and generation, chat, debugging, testing, documentation, local codebase awareness, and edition-specific code customization and Google Cloud integrations.

Source-Backed
Enterprise controls

Aider documents local configuration controls for model endpoints, API keys, SSL verification, timeouts, read-only files, and automatic acceptance behavior. It does not document organization-wide SSO, RBAC, or audit-log administration.

Source-Backed

Amazon Q Developer Pro supports workforce access through IAM Identity Center, including bulk subscription administration, cancellation, and usage tracking for managed users.

Source-Backed

Devin Enterprise documents organizational onboarding and administrative setup requirements.

Source-Backed

Gemini Code Assist Standard and Enterprise document managed workforce identities, federated sign-in and SSO guidance, IAM access controls, VPC Service Controls, and network security options.

Source-Backed
Privacy & data policy

Aider documents opt-in anonymous analytics and states that its analytics do not collect code, chat messages, keys, or personal information; analytics can be disabled.

Source-Backed

Amazon Q Developer documents how prompts, responses, code context, processing locations, storage regions, and tier-specific data handling apply to supported features.

Source-Backed

Cognition documents encryption in transit and at rest, role-limited production access, security monitoring, and privacy and intellectual-property controls for Devin; organization-specific retention and processing terms should still be confirmed during procurement.

Source-Backed

Gemini Code Assist Standard and Enterprise document prompt and code-context handling, telemetry boundaries, stateless prompt processing, encryption, and that customer data is not used to train models without permission.

Source-Backed
Integrations

Aider documents terminal-based use alongside editors plus a watch-files mode for IDE or editor integration; it also lists optional editor-specific paths while warning that third-party plugins may vary in maintenance quality.

Source-Backed

Amazon Q Developer documents integrations with GitHub and GitLab workflows, including feature development, code review, and project-specific rules; availability and maturity differ by integration.

Source-Backed

Devin documents integrations with source control, issue tracking, communication, and related development systems.
