## 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

## CodeRabbit

CodeRabbit is built around a specific problem: AI coding agents can now produce changes faster than human reviewers can read them. Instead of treating review as a nice-to-have, the product positions an automated reviewer as the validation layer between generated code and production. When a pull request opens, CodeRabbit reads the diff together with repository context — coding guidelines, related files, dependency graph — and posts review comments directly in the PR thread. Each comment can include a committable suggestion, and the bot will hold a conversation with the author, including coding agents, until the feedback is addressed and verified.

Beyond the review itself, the platform adds three layers. Triage turns an overwhelming queue into a prioritised Kanban-style board, ranking PRs by business impact and risk so safe, routine changes move quickly and risky ones get attention. Change Stack addresses explainability: semantic diffs, blast-radius context and architectural diagrams turn a thousand-line change into something a person can understand in minutes. Security runs scheduled deep scans and scans on every PR, verifies findings to reduce false positives, then opens a fix PR.

The target audience is engineering teams at scale — the site cites thousands of customers and tens of thousands of repositories. Reviews are customisable through configurable guidelines and review personalities (calmer or more assertive), and the tool learns from author replies so it stops repeating conventions the team has rejected. Pricing follows a freemium model with a free tier, a free trial and paid seats for teams.

**Pricing & Plans:** Freemium with a free trial, a free tier for smaller/open-source use, and paid per-developer plans. Higher tiers add triage, Change Stack and security features; enterprise pricing is available on request.

- **Automated PR reviews with context:** Every pull request gets line-level comments that draw on repository-wide context, coding guidelines and related files rather than just the diff in isolation.
- **Committable suggestions and agent loops:** Comments ship with one-click fixes, and CodeRabbit will iterate with human authors or coding agents until the feedback is resolved and re-verified.
- **PR triage and prioritisation:** Scores, ranks and routes incoming pull requests so high-impact changes are reviewed first and routine ones fast-track, with a board view of the queue.
- **Change Stack explainability:** Semantic diffs, blast-radius analysis and architecture diagrams make very large, agent-generated changes understandable in a few minutes.
- **Continuous security scanning:** Scheduled deep scans plus scans on every PR surface dependency vulnerabilities and codebase risks, verify them to cut false positives, and open fix PRs.

**Strengths:** Reviews are genuinely contextual, not lint-level pattern matching, so comments are usually actionable; Triage and Change Stack solve real scaling problems created by agentic coding rather than adding another dashboard; Integrates with the GitHub and GitLab workflows teams already use, with committable suggestions and agent loops; Free tier and trial make it easy to evaluate on a real repository before committing budget

**Limitations:** Value scales with team size — small projects may find the full platform heavier than needed; Review quality and noise level depend on tuning guidelines and profiles, which takes an initial investment; Deeper security and explainability features sit behind paid tiers
