fragments
Fragments is an open-source Next.js template that enables building AI-generated applications similar to Claude Artifacts or Vercel v0. It integrates with the E2B SDK to safely execute AI-generated code across multiple languages and LLM providers.

What fragments is
TypeScript/Next.js 14 full-stack template using Server Actions, shadcn/ui, and TailwindCSS. Leverages E2B SDK for sandboxed code execution, supports Python, Node.js, Vue, Streamlit, and Gradio; integrates with OpenAI, Anthropic, Google AI, Mistral, Groq, Fireworks, Together AI, and Ollama via Vercel AI SDK.

Best use cases
Implementation considerations
- Requires E2B API key and at least one LLM provider key (OpenAI, Anthropic, etc.); multi-provider setup adds environment variable overhead.
- E2B SDK handles code sandboxing—verify execution isolation and resource limits meet your risk tolerance before processing untrusted prompts.
- Customizing stacks (Streamlit, Gradio, Vue) requires E2B CLI and Docker knowledge; Dockerfile templates provided but non-trivial to extend.
- Rate limiting, KV store (Vercel), and Supabase auth are optional; production deployments should enable these for reliability and access control.
- Morph API integration for token-efficient code editing is optional and enabled by default; can be disabled via environment variables.
When to avoid it — and what to weigh
- Minimal security/compliance requirements unclear — E2B SDK security posture, audit trails, and compliance certifications are not detailed in provided data; requires direct vendor review before regulated workloads.
- Need for pre-built, no-code deployment — Requires Node.js, environment configuration, E2B and LLM API keys setup; not a SaaS drop-in or managed platform alternative.
- Offline-first or air-gapped requirements — Template depends on external LLM APIs and E2B sandbox infrastructure; local-only execution not supported by design.
- Seeking stable, long-term versioning — No release tags recorded; last commit 2026-07-03 suggests active development but unclear release cadence or semantic versioning discipline.
License & commercial use
Apache License 2.0 (Apache-2.0). Permissive OSI-approved license allowing commercial use, modification, and distribution with attribution and liability disclaimer.
Apache-2.0 permits commercial deployment and modification without vendor approval. However, commercial viability depends on E2B SDK licensing (not provided) and third-party LLM API terms (OpenAI, Anthropic, etc.); review those separately. No guarantee of support or indemnification from E2B for this template.

E2B SDK provides code sandboxing, but sandbox isolation guarantees, resource limits, and multi-tenancy safety are not detailed. API key exposure risk via client-side env vars (mitigated by NEXT_PUBLIC_ prefix convention). NEXT_PUBLIC_NO_API_KEY_INPUT disables user input for keys; disable in production. Supabase auth is optional; authentication not enforced by default. No rate limiting without KV setup. Audit logging and compliance posture unknown.
Alternatives to consider
Anthropic Claude Artifacts (managed service)
Official, fully managed, integrated into Claude UI; no self-hosting or API orchestration needed, but locked to Anthropic models.
Vercel v0 (managed service)
Enterprise-grade alternative with Vercel integration and proprietary models; closed-source, no customization, higher cost.
GPT Engineer (open-source, Python-first)
Python-centric code generation and execution; different stack philosophy; larger community for data science workflows but less web-first.
