• Works directly in Git repositories and can commit changes
• Multi-file edits, repository maps, lint, and test integration
• Many model providers and editor-independent terminal workflow
• Less visual than IDE agents
• Primarily conversational rather than multi-agent
• Recent development activity is lower than some newer tools

Agno is more of an AI agent platform than a direct Kiro replacement. It provides memory, knowledge integration, tools, monitoring, and deployment capabilities for production AI agents.

Pricing: Open source and self-hostable; hosted services may be offered separately.

• Memory, knowledge, and tool integration
• Model agnostic with monitoring and production deployment
• Self-hosting
• A framework for building agents, not a ready-made coding environment
• Requires development work to use

Self-hosted coding assistant focused on code completion and private inference infrastructure. Offers repository context and editor integrations. Main code outside the Enterprise directory is Apache-2.0; functionality under ee/ has separate commercial licensing.

Pricing: Open-source core with separately licensed Enterprise functionality.

• Operate code-completion infrastructure on private systems
• Repository context and multiple editor integrations
• Apache-2.0 core and enterprise deployment options
• Enterprise directory is separately licensed
• Focused more on completion than autonomous coding
• Development cadence is slower than several newer agents

MIT agentic coding platform for VS Code, JetBrains IDEs, and the command line. Supports more than 500 model options, bring-your-own API keys, local models, coding, debugging, planning, and codebase Q&A modes, an MCP marketplace, autonomous CI/CD, and mid-task model switching.

Pricing: Open-source tooling; model API usage and optional cloud features are separate.

• VS Code, JetBrains, and CLI support
• 500+ model options, BYOK, local models, and model switching
• Coding, architect, debug, MCP, and CI/CD workflows
• Large feature set can be complex
• Cloud features add another layer beyond local development
• Product changes rapidly

MIT coding agent focused on code generation, debugging, and day-to-day development workflows. The project provides a streamlined IDE-oriented experience and supports multiple programming languages; consult its current official repository for supported integrations and model backends.

Pricing: Open-source project; model usage depends on configured provider.

• Focused on common code generation and debugging tasks
• IDE-oriented workflow and multi-language support
• Rapidly growing project
• Younger ecosystem
• Less mature extension system than OpenCode or Cline
• Smaller integration ecosystem

CodeEdit is an MIT-licensed native macOS editor written in Swift, designed as a lightweight and fast development environment. Its built-in AI stack is less mature than Cursor's.

Pricing: Free and open source under MIT.

• Native macOS application
• Lightweight and fast
• Familiar editor foundation
• macOS only
• AI functionality is less mature
• Smaller extension ecosystem

Apache-2.0 orchestration layer that runs existing coding agents on your own machines and lets developers control them remotely from desktop, mobile, web, or CLI. Supports Claude Code, Codex, Cursor, OpenCode, Git workflows, GitHub triggers, and Slack/Discord integrations.

Pricing: Open-source self-hosted orchestrator; agents and model subscriptions are separate.

• Remote control of agents running on your machines
• Desktop, mobile, web, and CLI interfaces
• GitHub triggers and Slack/Discord integrations
• Requires separate coding agents
• More infrastructure than a single CLI
• Orchestration rather than code intelligence itself

Desktop application for launching coding agents in separate Git worktrees and reviewing their changes with diffs, IDE launching, port forwarding, and MCP. Supports Claude Code, Cline, Codex, Cursor Agent, and Gemini. Current code uses Elastic License 2.0, which is source available rather than OSI-approved open source.

Pricing: Source-available project; review Elastic License 2.0 terms.

• Parallel agents in isolated Git worktrees
• Diff review, IDE launching, port forwarding, and MCP
• Supports several popular external agents
• Elastic License 2.0 is not conventional open source
• Primarily macOS-focused
• Requires external agents

Apache-2.0 desktop app for coordinating coding agents in parallel, with isolated Git worktrees, MCP, built-in editor, CLI auto-detection, and support for more than 25 external coding agents.

• MCP, built-in editor, and CLI auto-detection
• Parallel agent workflows
• Most useful to teams running multiple agents
• Requires external agent tools
