Founders, product managers, designers, and small teams use Lovable to spin up landing pages, internal tools, MVPs, dashboards, marketplaces, and SaaS prototypes in minutes, then iterate by chatting with the editor instead of opening an IDE. Connect Supabase, Stripe, GitHub, and a custom domain, and you can ship a real, monetizable product the same afternoon you started it.

### Key Features:
- Prompt-to-app generation that produces React, Tailwind, and full backend code on the first turn
- Live visual editor with chat-based edits, version history, and instant rollback
- Built-in Supabase integration for auth, database, storage, and edge functions
- One-click GitHub sync so every project is owned, exportable, and self-hostable
- Stripe and payments wiring for paid products, subscriptions, and checkout flows
- Custom domain publishing with SSL and global CDN out of the box
- Team workspaces, role-based access, and shared credit pools for collaborative building

## Windsurf: The Agentic AI IDE for Modern Software Engineering Teams

Windsurf is the agentic AI code editor built for developers who want their IDE to do real work, not just autocomplete the next line. Originally launched as the flagship product of Codeium and rebranded to Windsurf in 2025 before being acquired by Cognition AI, Windsurf has rapidly become one of the most-used AI development environments in the world. The product is purpose-built for the agentic era of coding, blending a familiar VS Code-style editor experience with a deep planning agent called Cascade that can read your repository, understand intent, edit multiple files at once, run terminal commands, and verify changes against tests. Whether you are shipping a feature in a side project, refactoring a sprawling enterprise monorepo, fixing a tricky bug in a legacy codebase, or onboarding to a new repository, Windsurf gives you the tooling to move from idea to working code without leaving the editor or context-switching between chat windows and your terminal.

In day-to-day use, Windsurf feels like pairing with a senior engineer who happens to be very fast. Tab autocomplete delivers high-quality, multi-line suggestions as you type, with no usage credits consumed even on the free tier. Supercomplete predicts the next change, not just the next token, which makes it especially useful when you are mid-refactor. The Cascade agent handles longer, multi-step work like building features end to end, generating tests, executing commands in the integrated terminal, and reviewing diffs before committing. Codemaps, an indexed view of your repository, gives Windsurf context across your codebase so suggestions are grounded in your real architecture rather than a stale snippet. Windsurf supports the major programming languages developers actually use day to day, integrates with VS Code and JetBrains family IDEs, and runs natively on Mac, Windows, and Linux. With a free plan, Pro at fifteen dollars per month, Teams plans for collaborative engineering orgs, and an Enterprise tier with SSO, RBAC, and serious compliance posture, Windsurf scales from solo developers to large enterprise engineering teams.

### Key Features:

- Cascade agent for end-to-end agentic coding with multi-file edits, terminal commands, and test runs
- Tab autocomplete with high-quality multi-line suggestions and no credit usage on every tier
- Supercomplete predictive editing that anticipates the next change, not just the next token
- Codemaps repository indexing that grounds AI suggestions in your real architecture
- Native Windsurf Editor for Mac, Windows, and Linux based on a familiar VS Code experience
- Plugins and integrations for VS Code and JetBrains for teams that want to keep their current IDE
- SWE-1.5 and other in-house Cognition models tuned specifically for software engineering tasks
- Inline chat and side-panel chat for quick code questions and explanations
- Built-in support for Git workflows, diffs, and pull request preparation inside the editor
- Enterprise security with SSO, RBAC, SOC 2 Type 2 compliance, and FedRAMP and HIPAA paths available

### Ideal Use Case:

Windsurf is ideal for individual developers who want a faster, smarter editor than stock VS Code, founders and indie hackers shipping side projects on tight timelines, engineering teams that need agentic AI inside the IDE rather than another browser tab, and enterprise organizations that need a secure, compliant AI coding tool for regulated workloads. It is a strong fit for teams modernizing legacy codebases, accelerating greenfield development, onboarding engineers to unfamiliar repositories, automating repetitive refactors, and writing tests at scale. If you have outgrown plain autocomplete and want an editor that can plan, edit, and verify, Windsurf is the upgrade.

### Why Use Windsurf:

- Agentic Cascade workflows automate the multi-step work that traditional autocomplete cannot reach
- Free tier with unlimited Tab autocomplete makes it the lowest-friction agentic IDE to try
- Five dollars per month cheaper than Cursor on the comparable Pro plan
- Codemaps gives the model true repo-wide context, reducing hallucinated APIs and broken imports
- Built and maintained by Cognition AI, the team behind the Devin software engineering agent
- Native VS Code experience for engineers who already work that way, no relearning required
- Enterprise-grade security, compliance, and admin controls suitable for regulated industries
- Active product roadmap with frequent model and feature updates from the Cognition team

## Zed

Zed is an open-source code editor written in Rust by the team that built Atom and Tree-sitter at GitHub. Zed renders its entire interface on the GPU through a custom framework called GPUI, which is why Zed feels faster than Electron-based editors: independent tests show roughly a 0.6-second cold start and about 222 MB of idle memory, versus multi-gigabyte footprints elsewhere. Beyond speed, Zed is built for agentic coding, running AI agents through an open Agent Client Protocol so models from Anthropic, OpenAI, and others work natively. It also keeps the real-time multiplayer editing the founders pioneered with Atom's Teletype.

**Production credibility:** Founded in 2019 by Nathan Sobo, Antonio Scandurra, and Max Brunsfeld, the team that led Atom at GitHub and created Tree-sitter (the incremental parser now used by Neovim, Helix, and GitHub code search). Zed has raised about $44.5M total, including a $32M Series B led by Sequoia Capital in August 2025; earlier investors include Redpoint Ventures, Root Ventures, and Matchstick Ventures, plus angels Dylan Field (Figma) and Tom Preston-Werner (GitHub). Zed open-sourced its GPUI rendering framework and authored the Agent Client Protocol, an open standard for connecting AI agents to editors.

### Key Features
- Written from scratch in Rust with a custom GPU-rendered UI framework (GPUI) instead of Electron.
- Independent benchmarks report a ~0.6s cold start and ~222 MB idle RAM, well below Electron-based editors.
- Founded in 2019 by Nathan Sobo, Antonio Scandurra, and Max Brunsfeld, the creators of Atom and Tree-sitter.
- Raised ~$44.5M total, including a $32M Series B led by Sequoia Capital (Aug 2025).
- Authored the Agent Client Protocol (ACP), an open standard so any AI agent can plug into the editor.
- Runs native AI agent threads in parallel, bounded by your API rate limits rather than editor architecture.
- Real-time multiplayer editing and channels, descended from the team's work on Atom's Teletype.
- Free and open-source under the GPL; works with multiple model providers (Anthropic, OpenAI, and others).

### Ideal Use Case
Use Zed when you want a fast, keyboard-driven editor for daily coding, pair programming over the network, or directing AI agents yourself rather than handing the entire task to a chat box.

### How Zed differentiates
Versus VS Code, Zed is dramatically lighter and faster because it avoids Electron, but its extension ecosystem is far smaller and younger. Versus Cursor, Zed expects you to direct AI agents and prizes raw editor speed, while Cursor (a VS Code fork) leans into AI doing more of the code generation. Versus Neovim, Zed offers a modern GUI, built-in collaboration, and agent support without heavy configuration, though Vim users give up some muscle memory and depth. The trade-off is maturity: Zed reached 1.0 only recently, so some languages and plugins still lag the incumbents.

### FAQ

**Q: Is Zed free?**
A: Yes. Zed is open-source under the GPL and free to use. Paid plans cover hosted collaboration features and managed AI usage, but the editor itself is free.

**Q: Zed vs Cursor: which should I pick?**
A: Zed is a from-scratch Rust editor focused on speed and on letting developers steer AI agents directly, and it can run multiple agents in parallel. Cursor is a VS Code fork that automates more of the code generation. Pick Zed for raw speed and control; pick Cursor if you want AI to do more of the heavy lifting inside a familiar VS Code layout.

**Q: Who founded Zed?**
A: Nathan Sobo, Antonio Scandurra, and Max Brunsfeld, the team that built Atom at GitHub and created Tree-sitter. The company was founded in 2019.

**Q: How much has Zed raised?**
A: About $44.5M total, including a $32M Series B led by Sequoia Capital in August 2025, with participation from Redpoint, Root Ventures, and angels including Dylan Field and Tom Preston-Werner.

**Q: Does Zed work on Windows?**
A: Zed launched on macOS and Linux first; a Windows build has been in progress and rolling out. Check the current download page for the latest platform status.

### tl;dr
Zed is an open-source, GPU-accelerated code editor written in Rust by the creators of Atom and Tree-sitter. It pairs benchmark-leading startup speed and low memory use with native, parallel AI agents via the open Agent Client Protocol. Backed by a $32M Sequoia-led Series B (~$44.5M total).

baro turns one prompt into a pull request. You're in your repo, you type something like "add JWT auth with role-based access" or "write unit tests for every service under src/", and you walk away. When you come back there's a branch, a diff, and an open PR with a summary of what changed.

The thing that makes it different from the single-session coding tools (Claude Code, Cursor's agent, and so on) is that baro doesn't run one agent. It plans the goal into a **dependency graph** of small stories, then runs the independent ones in **parallel** — each story is its own agent in its own subprocess. There's no big orchestrator function in the middle calling the shots; every part of the run is a participant on a **shared event bus** (built on an open-source framework called Mozaik), and they coordinate by reacting to each other's events. That sounds academic, but the payoff is practical: adding a new behavior is just a new participant rather than a rewrite, and nothing bottlenecks when you push past a handful of concurrent agents.

A run has a small cast, and each one does exactly one job:

**Architect** makes the cross-cutting decisions up front — file paths, schema names, API shapes — and pins them, so thirty parallel agents don't each invent their own conventions.

**Planner** breaks the goal into the story DAG.

**Story agents** do the actual coding, in parallel, each on its own slice.

**Critic** grades every agent's work against the story's acceptance criteria each turn, and feeds corrections back in when something's off.

**Librarian** indexes what one agent discovers so its siblings don't re-explore the same files.

**Sentry** flags when two concurrent agents reach for the same file.

**Surgeon** re-plans on the fly when a story fails — splits it, adds a prerequisite, rewires the graph.

**Finalizer** runs your build, then opens the PR with a story table and stats.

You don't have to think about any of that — you type a goal and watch it happen in a live terminal UI (story status, agent logs, the DAG, token counts). But it's all there if a run goes sideways and you want to understand why.

One more thing that matters if you're cost-conscious: baro isn't locked to one model vendor. The \`--llm\` flag picks the backend for the whole run — Claude (through the Claude Code CLI, billed against a Claude subscription), OpenAI Codex (through the Codex CLI, billed against a ChatGPT subscription), or OpenAI's API directly. There's also a \`--llm hybrid\` preset that sends the cheap-but-careful upstream phases (Architect, Planner) to one model and the high-volume parallel coding work to another — on a real refactor that cut the subscription footprint to about a third of running everything on one premium model. Every phase has its own override flag if you'd rather mix it yourself.

A concrete run, so this isn't hand-waving: I pointed it at a NestJS service with one prompt — "write a full Jest unit suite for every service, controller, guard, listener, scheduler, mapper, decorator, filter, helper, and validator under src/." It planned 33 stories, ran them in parallel across three dependency levels, hit Anthropic's usage cap halfway through at 3am, paused, resumed in the morning, and finished: 808 tests, 83.5% branch coverage, 32 files, one PR. The quality gate filed zero phantom bug issues.

It shines on work that decomposes — test suites, multi-file features, mechanical refactors, anything where "many small parallel changes" beats "one careful sequential edit." For a one-line typo fix, use \`--quick\` (it skips the planning machinery and runs a single agent) or honestly just edit the file yourself. Every run writes a full audit log to \`~/.baro/runs\`, so when something breaks there's a trail.

Install is one line — \`npm install -g baro-ai\` — and you need at least one of the Claude CLI, the Codex CLI, or an OpenAI key signed in. It runs on macOS, Linux, and Windows, and it'll open the PR for you if you have the \`gh\` CLI. Source is on GitHub (jigjoy-ai/baro), docs at docs.baro.rs.


### FAQ

**Q: What is baro?**
A: baro is an autonomous parallel coding agent CLI that turns a single prompt into a pull request. Rather than running one agent in one session, baro plans the goal into a dependency graph of small stories and runs the independent ones in parallel — each story is its own agent in its own subprocess.

**Q: How is baro different from Claude Code, Cursor, or Devin?**
A: Claude Code and Cursor's agent run a single sequential agent. Devin orchestrates one agent over multiple sessions. baro is the parallel-agent execution model — dozens of agents run concurrently against a story DAG, coordinated through a shared event bus rather than a central orchestrator. Result: faster wall-clock time on decomposable work (test suites, multi-file features, mechanical refactors).

**Q: Which LLM does baro use?**
A: baro is not locked to one model vendor. The `--llm` flag picks the backend — Claude (via the Claude Code CLI), OpenAI Codex (via the Codex CLI), or OpenAI's API directly. There's also a `--llm hybrid` preset that uses different models for different phases to cut cost.

**Q: Is baro open source?**
A: Yes — source is at github.com/jigjoy-ai/baro and docs at docs.baro.rs. Install via `npm install -g baro-ai`.

**Q: When should I use baro vs single-agent tools?**
A: baro shines on work that decomposes — test suites, multi-file features, mechanical refactors. For a one-line typo fix, use `--quick` or just edit the file yourself. baro is purpose-built for "many small parallel changes" rather than "one careful sequential edit."

### tl;dr

baro is the autonomous parallel-coding-agent CLI that turns one goal into a pull request. Plans the work into a story DAG, runs independent stories in parallel, coordinates via shared event bus. Works on Claude Code, OpenAI Codex CLI, or OpenAI API. Open-source (github.com/jigjoy-ai/baro). Built by Jigjoy AI in Serbia.

## Tessl

Tessl is the AI-native software development platform built by Guy Podjarny (founder of Snyk). Tessl's pitch is spec-driven development — engineers write a specification of what software should do, and Tessl generates, tests, and maintains the implementation across multiple LLM backends. Tessl raised approximately $125M Series A at unicorn valuation and is positioned as the production-engineering counterpart to chat-based coding tools like Cursor and Devin.

**Production credibility:** Approximately $125M Series A at $750M valuation led by Index Ventures with Accel, GV (Google Ventures), and Boldstart participating. Founded by Guy Podjarny (founder + ex-CEO of Snyk, prior CTO of Akamai's Web Application Security business). London HQ. Spec-driven approach addresses the production-engineering reliability gap that chat-based coding tools haven't solved.

### Key Features
- Spec-driven AI coding — engineers write specs, Tessl generates the implementation
- Multi-model backend support across Anthropic, OpenAI, and others
- Test generation and maintenance baked into the spec workflow
- Founded by Guy Podjarny (founder + ex-CEO of Snyk)
- $125M Series A at $750M valuation; Index Ventures lead with Accel, GV, Boldstart
- London HQ; ex-Snyk and ex-Akamai security engineering DNA
- Positioned for production engineering rather than prototyping or single-developer use

### Ideal Use Case
Production engineering teams that have outgrown chat-based AI coding for prototyping and want spec-driven development for maintained, tested, multi-developer codebases. Particularly strong fit for enterprise teams where reliability and audit trails matter.

### How Tessl differentiates
Cursor and Devin focus on chat-based assistance and single-task agent execution — strong for prototyping and indie development. The production-engineering reliability gap (specs, tests, long-term maintenance, multi-developer coordination) isn't well addressed by chat-driven tools. Tessl's spec-driven approach inverts the workflow — the spec is the source of truth, implementations are regenerated as specs evolve, tests are bound to spec assertions. The trade-off is steeper learning curve than chat tools; the upside is engineering-process discipline that production teams can sign off on.
