Mainbrella
Mainbrella provides API-managed Linux workspaces for AI agents to execute commands, transfer files and open web previews. Applications can select runtime images, inspect stdout and exit codes, or connect by SSH and a browser terminal. Fixed monthly plans cap compute and sessions, while saved-workspace features preserve selected filesystem state.
Best for: Developers integrating command execution and temporary isolated filesystems into coding agents or tool-calling applications.
- 02
Frederick
Frederick provides AI agents that build software, run background jobs, and operate browser sessions on behalf of startup teams. The product bundles coding agents, scheduled background workers, shared multiplayer workspaces, and hosted compute so founders can ship apps and automate go-to-market tasks from one control plane.
Best for: Founders and small teams who want autonomous coding, browser, and background agents instead of stitching separate dev and ops tools.
- 03
GitHub Copilot
GitHub Copilot is GitHub's AI coding agent suite spanning IDE completion, chat, agent mode, code review, CLI, and cloud agents. Individual plans meter GitHub AI Credits for chat and agent usage while Free offers limited access and paid tiers raise credit allotments.
Best for: Developers who want Copilot embedded in GitHub workflows from local IDE assistance through cloud agents.
- 04
Party
Party is a Y Combinator-backed workspace where product teams and fleets of coding agents build in the open together. Teams describe work in natural language, coordinate humans and agents in one thread, and ship previews with Mac, iOS, and Android clients.
Best for: Product and engineering teams that want a shared agentic workspace instead of siloed AI chats.
- 05
Kiro
Kiro is an agentic engineering environment from AWS that turns prompts into specs, validates code, and runs parallel agents across large repos. It offers a desktop app, CLI installer, and credit-based paid tiers with access to open-weight and premium models.
Best for: Developers and small teams who want spec-driven AI coding agents with downloadable IDE tooling.
- 06
Brnch
Brnch is code hosting built for people and AI-agent sessions, with revision-bound approvals and signed merge receipts. It records who authored and approved a change and which independent checks ran on the merged tree. MCP clients can inspect repositories, while paid plans add hosted coding agents, AI review and previews.
Best for: Teams wanting traceable agent contributions, protected merges and an assistant connection to hosted repository data.
- 07
CodeGPT
CodeGPT is an AI coding agent extension for VS Code, JetBrains, and Visual Studio that supports multiple frontier models with BYOK or bundled credits. It emphasizes plan-then-build agentic workflows, MCP integrations, autocomplete, and team billing with pooled credits.
Best for: Individual developers and teams who want model-flexible IDE agents with visible planning steps and optional bring-your-own-key control.
- 08
AI Native Dev Landscape
Tessl is an agent enablement platform for managing skills, plugins, reviews, and evals so teams can standardize how coding agents work.
Best for: Engineering teams adopting agentic development who need governed skills, reviews, and shared context.
- 09
Armature
Armature helps developer tools get discovered and used by coding agents through discoverability services and a self-serve usability product. Discoverability measures agent picks and drafts doc and SDK changes, while MCP Analytics and evals replay sessions and catch regressions on every deploy.
Best for: Developer-tool companies that want coding agents to recommend their product and need telemetry on MCP usage quality.
- 10
Mem0
Mem0 provides persistent memory infrastructure for AI agents and applications so context survives across sessions, users, and agents. The platform offers hosted plans with SDK integration plus open-source options for developers building production agents that need durable recall.
Best for: Agent builders and app teams that need hosted memory layers with defined add and retrieval quotas.
