## Arcjet

Arcjet started life as a developer-friendly security layer for web applications and has expanded into runtime security for AI agents. Instead of only checking identity at the door, it evaluates every step an agent takes: which tool is being called, with which typed arguments, by which actor, and in the context of the steps that came before. That lets teams stop unauthorized refunds, unexpected data access, runaway token spend and sequence drift that no single step would have flagged on its own.

The platform combines classic application protections - WAF, bot detection, rate limiting, signup form protection and email validation - with agent-specific controls such as prompt injection detection, tool and MCP authorization, sensitive information detection and data loss prevention. Detection for sensitive data can run locally in your environment so regulated payloads never leave your infrastructure, while decisions and policy versions stream out to SIEM tools like Splunk, Datadog, Panther and Cribl for evidence.

Arcjet ships SDKs for JavaScript and Python ecosystems (Next.js, Astro, Express, Fastify, NestJS, Nuxt, SvelteKit, Hono, Flask, FastAPI, Bun, Deno and more) plus integrations for agent frameworks including LangChain, LangGraph, CrewAI, Google ADK, Mastra, OpenAI Agents, Vercel AI SDK and the Claude Agent SDK. It also offers an MCP server, a CLI and skills for coding agents such as Claude Code, Codex and Cursor. A free trial is available, with paid plans and custom/enterprise pricing on request.

**Pricing & Plans:** Free trial available, then paid plans with custom pricing for larger deployments. Enterprise and volume pricing is quoted on request. Check the official pricing page for current tiers and usage limits.

- **Agent action policy enforcement:** Wrap agent tool calls and get a typed decision - allow, block, redact or hold for review - before the tool actually executes, based on actor, role, route and typed inputs.
- **Prompt injection detection:** Screen user input, fetched web pages, API responses and tool output for hostile instructions before anything reaches the model context.
- **Sensitive information and DLP:** Detect and strip names, addresses, national IDs, bank and card numbers before they reach model context, logs or third-party tools, with optional in-process local detection.
- **Web app protections:** Bot protection, WAF rules, rate limiting, signup form protection and email validation to keep public endpoints and signup flows clean.
- **Audit and observability:** Every decision, policy version and actor is retained as evidence and streamed to Splunk, Datadog, Panther, Cribl or your own analytics warehouse, with OpenTelemetry agent traces.

**Strengths:** Evaluates the whole agent run, not just a single request, which catches sequence drift and multi-step abuse; Detection can run in-process so sensitive data does not have to leave your environment; Broad SDK and agent-framework coverage, including an MCP server, CLI and coding-agent skills; Decisions and policy versions stream to common SIEM and observability stacks for compliance evidence

**Limitations:** Requires code changes inside your application rather than a purely network-level gateway deployment; The breadth of controls and frameworks means a real learning curve for smaller teams; Advanced enterprise governance and custom retention options are quote-based rather than self-serve

## Replit

Replit began as one of the most popular browser-based coding environments and has evolved into an AI-first app and website builder. You describe what you want to build, and Replit's agent plans the work, writes production-ready code across the stack, iterates on feedback, and can publish the running app for you. Because everything happens in the cloud, there is no toolchain to install and no local environment to maintain.

The platform pairs the agent with the infrastructure a real product needs: authentication, a managed database, hosting, monitoring and more than a hundred integrations such as OpenAI, Stripe and Google Workspace. Recent releases added intelligent model routing that cuts the average cost of complex builds, an infinite canvas for visual design iteration and multi-user collaboration features aimed at teams.

Replit suits a very wide audience. Founders use it to go from idea to landing page or prototype in an afternoon, product managers build interactive demos instead of static specs, designers move straight from concept to functioning UI, and engineering teams use it to spin up internal tools quickly. A generous free mode lets people create without token costs, while paid plans unlock more powerful models, more storage and commercial usage.

**Pricing & Plans:** There is a free mode with limited chat hours and projects. Replit Core is about $20/month (about $18/month billed annually), and Replit Pro is roughly $90–100/month billed annually for commercial work. Enterprise plans add SSO/SAML, SOC 2 controls and admin features.

- **Agentic app generation:** Describe the product you want and the agent plans, codes, tests and iterates on a working full-stack application.
- **Built-in full-stack infrastructure:** Authentication, databases, hosting and monitoring work out of the box, so apps scale without separate DevOps work.
- **Free mode for experimenting:** A no-cost mode lets you brainstorm and build without spending tokens before upgrading to stronger models.
- **100+ integrations:** Connect services such as OpenAI, Stripe and Google Workspace in minutes rather than writing glue code.
- **Team and enterprise controls:** Multi-user collaboration, SSO/SAML, SOC 2 alignment and admin controls support professional and regulated use.

**Strengths:** No local setup; everything runs and deploys in the browser; Agent handles full-stack code, infrastructure and publishing; Free mode makes experimentation accessible; Strong collaboration, integrations and enterprise security controls

**Limitations:** Complex or highly custom architectures may still need manual engineering; Agentic build costs can rise quickly on heavier projects; Less control over low-level infrastructure than managing your own stack
