Lovable.dev — harness
Cross-listing of Lovable at the harness layer. Swedish startup (Stockholm) that grew out of GPT Engineer (Anton Osika). Builds full-stack React/Supabase apps from prompts; AI handles git, deploys, DB. The Coding-agent-memory row remains canonical for memory.

When to use
Optimised for: non-engineer prompt-to-deployed-webapp
Anti-fit: React + Supabase stack only; less control than custom IDE
Pros & cons
Pros
Highest-revenue European AI-coding startup of 2025; non-engineer onboarding curve is the smoothest in the field.
Cons
Stack-locked (React + Supabase); product matures very quickly so prior versions break; high churn risk if model costs spike.
Claims & capabilities
Reportedly $200M+ ARR by Q3 2025 (founder claim); $200M Series A at $1.8B val mid-2025 (Accel led); fastest-growing European AI startup.

- Claude Code (Anthropic) T1
Anthropic's agentic coding tool: Claude as a coding agent in the terminal, IDEs (VS Code, JetBrains), desktop app, web/mobile, GitHub and Slack. Context via CLAUDE.md, skills, hooks, subagents and MCP servers.
- Cursor (IDE) T1
AI-first IDE that forked VS Code; Composer (multi-file edit) and Agent Mode (long-running coding agent) are its flagship surfaces. Memory layer = .cursorrules / Rules; recall via repo-aware Context Engine. Anysphere (parent) raised $900M Series C at $9.9B in May 2025; acquired by SpaceX (announced 2026-08-14, terms undisclosed), product continues under the Cursor brand.
- OpenAI Codex CLI T1
OpenAI's actively developed OSS terminal coding agent (Apr 2025), now written in Rust (codex-rs replaced the original TS CLI); also IDE extension + desktop app. Separate from the Codex Web cloud agent and the retired 2021 Codex model API. The codex mcp-server command (Codex as an MCP server) was deprecated on 2026-08-24 and removed in CLI 0.154.0 (2026-09-09); OpenAI points integrations to the experimental Codex app server, and codex mcp still connects Codex to external MCP servers.
- Opencode (SST) T2
SST team's open-source terminal coding agent — TypeScript, multi-model, MCP-native. Released 2025; explicitly positioned as a permissively-licensed Claude Code alternative. Memory via AGENTS.md (the emerging cross-harness convention).
- Bedrock AgentCore (AWS) T2
AWS Bedrock AgentCore — managed runtime to deploy + scale + observe agents. Multi-component: Runtime, Identity, Memory, Gateway, Browser, Code Interpreter, Observability. Distinct from Bedrock Agents (older fixed-config product); AgentCore is the 2025 framework-agnostic runtime for any agent (LangGraph, CrewAI, Strands, OpenAI Agents SDK).
- GitHub Copilot (Agent Mode) T1
The original AI coding assistant (Copilot in editor; 2021). 2025 evolved into a full agentic surface: chat, completions, Agent Mode (multi-step), and Copilot Workspace. Backed by Microsoft. Distinct row from Workspace — this row covers the everyday in-editor + agent mode product, Workspace covers the hosted spec-driven workflow.
