v0 by Vercel alternatives (2026)

Free to self-host and cheapest at scale; billed per full run, not per credit.

A flat $20/mo platform fee with unlimited runs (AI tokens metered separately) makes budgeting more predictable than v0 by Vercel's per-credit burn.

Built around multi-agent "teams" with a transparent dual meter.

Biggest free tier (5,000 credits/mo) and strong for data-heavy flows.

The most hands-off "AI employee" with voice/phone, if you want done-for-you.

AI coding agent built into a VS Code-style editor. Cursor combines inline Tab autocomplete, an in-editor Agent that edits across files, and Cloud/Background Agents that run remotely (launchable from the editor, Slack, GitHub, or via API) to fix bugs and open pull requests on their own.

Devin is Cognition's autonomous AI software engineer. You assign it a task or ticket (via web, Slack, Linear/Jira, or API) and it plans, writes code, runs commands in its own cloud VM, and opens pull requests largely without supervision. I

AI coding agent and pair programmer embedded in your IDE, terminal, and GitHub. Offers inline code completions, chat, an autonomous agent mode, a cloud-based coding agent that opens pull requests, and automated code review, with a choice of models from OpenAI, Anthropic, and Google.

Enterprise autonomous software development platform. Blitzy orchestrates 3,000+ specialized AI agents in parallel across multiple frontier models (Claude, GPT, etc.), grounding them in a knowledge graph it reverse-engineers from your existing codebase to autonomously build, refactor, and modernize software at scale.

Lovable is an AI app and website builder built around "vibe coding": you describe what you want in plain language and it generates a working full-stack app with a React/Tailwind frontend, Supabase backend, Stripe payments, and GitHub sync. It is prompt-to-app, with usage metered in credits per AI message. The company raised a $330M Series B in 2025.

Base44 is a chat-based, no-code AI app builder that turns plain-language prompts into full-stack web apps, handling the database, authentication, backend functions, and deployment behind the scenes. Acquired by Wix in June 2025, it targets non-developers who want working internal tools and SaaS-style apps without writing code. Pricing runs on a two-currency credit system: message credits for AI build prompts and integration credits consumed when end users trigger features like LLM calls, email, or file uploads.

CodeRabbit is an AI code-review agent that auto-reviews every pull request, leaving line-by-line comments, summaries, and one-click autofixes. It plugs into GitHub, GitLab, Azure DevOps and Bitbucket, and also runs reviews in your IDE and CLI before code is even pushed. Pricing is per developer, with a free tier and free reviews forever on public repos.

Botpress is a no-code AI agent and chatbot builder pairing a visual Studio with a code-first developer kit (ADK). It deploys agents to channels like WhatsApp, Messenger, Slack and web chat, and bundles the underlying LLM cost into a per-conversation price with no markup. Pricing is per conversation, billed in monthly packs once you exceed your plan allowance.

Anthropic's agentic coding tool that lives in your terminal, IDE (VS Code, JetBrains), and the web. It reads your whole codebase, edits files, runs commands, and ships changes through git on its own. Access comes bundled with a Claude Pro/Max subscription or via pay-as-you-go API usage on a Claude Console account.

OpenAI's agentic coding tool that runs as a terminal CLI, an IDE extension, a cloud agent, and inside ChatGPT, all sharing the same account. It is not sold on its own: access is bundled into ChatGPT subscriptions (Plus, Pro, Business, Enterprise) and is also available pay-as-you-go through the OpenAI API with an API key. It runs OpenAI's GPT-5.x and GPT-5.x-Codex models to read, write, run, and refactor code across local and cloud environments.

Windsurf is an agentic AI IDE built around Cascade, an autonomous coding agent that reads, edits, and runs your codebase across multiple files. It is one of the leading rivals to Cursor and was acquired into the Cognition (Devin) ecosystem. As of March 2026 it moved from a monthly credit pool to daily and weekly usage quotas, with extra usage billed at per-token model API prices.

Cline is an open-source (Apache 2.0) autonomous coding agent that runs as a VS Code extension, a JetBrains plugin, and a CLI. The extension itself is free with no subscription or seat fee; you pay only for AI model usage, either by bringing your own provider API keys or by buying credits through the optional Cline provider. It emphasizes no vendor lock-in, a Plan/Act workflow with human approval, and an MCP marketplace for connecting tools.

Aider is a free, open-source AI pair programmer that runs in your terminal and edits code in your local Git repo with automatic commits. The tool itself costs nothing; you bring your own LLM API key and pay the model provider directly, so spend scales with usage. It connects to almost any model, including local ones via Ollama for near-zero cost.

Voiceflow is a no-code/low-code platform for designing, building, and deploying AI chat and voice agents on a visual canvas. It targets agencies and businesses that want to ship customer-facing assistants across web, voice, and messaging channels without writing code, while keeping control over LLM choice, knowledge bases, and tools. Pricing moved to a unified credit model (April 2025) where a monthly plan fee includes a credit allowance and usage is metered against it.

OpenAI's visual, drag-and-drop toolkit for building, deploying, and optimizing AI agents without standing up your own orchestration layer. It bundles Agent Builder (a node-based canvas for multi-agent workflows with guardrails), ChatKit (embeddable chat UI), Connector Registry (managed data connectors), and Evals. There is no separate product fee: you build for free and pay only standard OpenAI API usage when your agents actually run.

Stack AI is a no-code, drag-and-drop platform for building enterprise AI agents and workflows that connect LLMs to internal data sources, documents, and apps. It leans hard on governance: on-prem/VPC deployment, SSO, access control, and SOC 2, HIPAA, and GDPR compliance. It targets regulated teams (finance, healthcare, legal) that need agents without writing code.

Dify is an open-source platform for building LLM apps, agentic workflows and RAG pipelines through a visual canvas, with a hosted cloud tier and a free self-hostable Community Edition. It blends a no-code/low-code builder with backend-as-a-service APIs, native MCP (client and server), and integration with hundreds of model providers, so teams can ship chatbots, agents and workflows without wiring infrastructure from scratch.

Taskade is an all-in-one AI productivity workspace (tasks, docs, mind maps, chat) that doubles as a no-code builder for custom AI agents and automations. You assemble agents, deployable apps, and multi-step automations against your project data, and the platform bills on a tiered plan that bundles a fixed monthly allotment of "AI credits" consumed by agent and automation runs across 15+ models (GPT, Claude, Gemini).

Text.com is the parent company behind LiveChat (agent-driven live chat helpdesk) and ChatBot (a no-code visual bot builder), now converged into one per-seat support suite. ChatBot lets non-developers build automated chat flows with a drag-and-drop builder plus an AI Agent trained on your content, while LiveChat handles human agent handoff, visitor tracking, and proactive campaigns. Both bill per agent seat and bundle a small monthly allotment of AI resolutions, charging per-resolution overages beyond it.

Augment Code is an AI coding agent built for large, complex, real-world codebases. Its differentiator is a "Context Engine" that indexes an entire repo so its agent (Auggie) can generate, review and manage code with deep codebase awareness across VS Code, JetBrains, Vim/Neovim and a CLI/TUI. As of October 20, 2025 it moved from message-based to fully credit-based pricing, where every plan is a pool of credits spent across models and agent activities, and each model consumes credits at a different multiplier.

Bubble is a full-stack visual no-code platform for building production web and mobile apps without writing code, covering UI, database, and backend workflows. It moved to a workload-based pricing model: plans bundle a monthly allowance of "workload units" (WU) that meter every backend operation, and usage beyond the allowance is billed as overage. It is a builder for finished apps, not an AI agent platform; AI capabilities exist via plugins and its API connector.

CustomGPT.ai is a no-code platform for turning your own content (1,400+ file types plus connectors like Google Drive, SharePoint, Notion, Zendesk and HubSpot) into custom RAG chatbots/agents you can embed, share, or call via API. It targets businesses that want an accurate, hallucination-resistant support or knowledge agent without engineering, and bills on a per-query model rather than per-seat.

Softr is a no-code platform for building client portals, internal tools, and web apps on top of a database (its own Softr Database, Airtable, Google Sheets, or external REST APIs). It targets non-developers who assemble apps from pre-built blocks with permissions, user groups, and payments, rather than writing code or wiring a backend. Increasingly AI-forward: it ships an AI app builder and a hosted MCP server that lets AI tools read/write Softr data.

Glide is a no-code platform that turns spreadsheets and databases (Glide Tables, Google Sheets, Airtable, Excel, SQL) into custom mobile and web business apps. It has pivoted hard toward AI: the Glide Agent can generate a working app from a prompt, and you can embed AI actions (extract data, draft emails, transform text/audio/images) into app workflows. Pricing is a flat monthly plan plus usage-based "updates," where most data writes to external sources and API/workflow actions are metered.

As of mid-2026 vellum.ai hosts "Vellum: Your Personal Intelligence" — an open-source (MIT) personal AI assistant marketed as an "AI chief of staff for high-agency individuals." It lives in Vellum Cloud (or self-hosted), has its own identity/email, a persistent multi-type memory layer, and acts in the world: triages email, manages calendar, posts to Slack/X, updates Linear, makes real phone calls, runs web search, and even vibe-codes small web apps. Capabilities extend via installable "skills" (a catalog at skills.sh incl. Gmail, Slack, DoorDash, Amazon) and via user-added MCP servers (Linear, GitHub, Notion, etc.). NOTE: this is NOT the older Vellum LLMOps/prompt-engineering-and-workflows developer platform that previously occupied this domain; that product appears to have been replaced/repositioned, so any "Pro $500/mo, prompt/workflow execution limits" pricing you find for "Vellum" is stale.
