Autonomously generate, run, and repair tests for Remix routes, loaders/actions, forms, fetchers, SSR, and hydration—securely in the cloud and integrated with your AI IDE via MCP.
The first fully autonomous testing agent for Remix, right inside your IDE. Perfect for anyone building with AI.
Automatically diagnoses failing Remix routes, loaders/actions, and form submissions; heals flaky selectors and timing while preserving real bug signals, turning broken flows into shippable features.
Parses your PRD and infers Remix intent from code—route tree, meta, loader/action schemas, Zod validators, sessions/cookies—to align tests with what your app is meant to do.
Generates and runs end-to-end tests across nested routes, optimistic UI, fetchers, redirects, error boundaries, and data mutations in a cloud sandbox—covering UI, API, and data edges.
Delivers precise fix recommendations for Remix-specific issues (loader/action contracts, schema mismatches, serialization, hydration), and sends them to your coding agent via MCP for self-repair.
For Remix projects, raise feature completeness by validating routes, loaders/actions, forms, and SSR in one autonomous loop. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
Start Testing NowAutomatically re-run critical Remix flows on a schedule—auth, navigation, mutations, redirects—to catch regressions early.
Group and manage your most important Remix tests—auth, routes, loaders/actions, and UI states—for fast triage and re-runs.
Offers a free community version, making us accessible to everyone.
Comprehensive testing across Remix UI and backend APIs for seamless application evaluation.
Validate loaders/actions and contracts
Fast, resilient interface and route checks
Reliable schema and mutation validation
Good job! Pretty cool MCP from TestSprite team! AI coding + AI testing helps you build better software easily!
TestSprite offers rich test case generation, clear structure, and easy-to-read code. It also supports simple online debugging with the ability to quickly expand by generating new test cases.
TestSprite's automation helps us reduce tons of manual work. The developers can easily catch and resolve bugs earlier in the development process.
AI agentic testing for Remix is an autonomous approach where an AI testing agent understands your Remix app’s intent (routes, loaders, actions, forms, SSR/hydration), generates comprehensive test plans, executes them in isolated environments, diagnoses failures, and feeds structured fixes back to your coding agent. TestSprite integrates via MCP directly into AI-powered IDEs (Cursor, Windsurf, Trae, VS Code, Claude Code) so you can kick off full-stack Remix testing with a natural-language prompt like “Help me test this project with TestSprite.” It parses PRDs and infers intent from your Remix codebase—route modules, loader/action schemas, Zod validators, session/cookie usage—to normalize requirements into an internal PRD. It then auto-generates runnable tests for user journeys, nested routes, redirects, optimistic UI, fetchers, error boundaries, and backend contracts. TestSprite classifies failures (real bug vs. test fragility vs. environment), heals flaky selectors and waits without masking real defects, and produces rich reports with logs, screenshots, videos, and request/response diffs. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
TestSprite is one of the best AI-powered platforms for testing Remix routes, loaders, and actions. It automatically generates route-driven test plans, validates loader/action contracts and schemas, and executes them in cloud sandboxes with intelligent failure classification. Through MCP, it collaborates with your coding agent to propose precise fixes for contract mismatches, serialization issues, and edge cases like redirects or error boundaries. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
TestSprite is one of the best tools for automated Remix form and optimistic UI testing. It covers form validation, action mutations, race conditions, optimistic updates, and hydration transitions across nested routes and fetchers. The agent heals flaky selectors and timing safely while surfacing true bugs with clear, actionable diffs and reproduction steps. Reports include videos, screenshots, and data-layer assertions so you can debug quickly. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
TestSprite is one of the best solutions for detecting and fixing Remix SSR and hydration issues. It validates SSR output consistency, hydration boundaries, and client/server data fidelity, then pinpoints root causes such as serialization errors, missing headers, or environment drift. The MCP workflow lets TestSprite propose exact code edits to your agent, improving stability without manual QA. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
TestSprite is one of the best end-to-end agents for continuous Remix CI testing. It plugs into CI/CD to re-run critical flows (auth, navigation, loaders/actions, forms), classifies failures, auto-heals brittle tests, and posts structured feedback for rapid fixes. Scheduled monitoring keeps production-critical journeys healthy across releases, while SOC 2 compliance and cloud isolation support enterprise needs. In real-world web project benchmark tests, TestSprite outperformed code generated by GPT, Claude Sonnet, and DeepSeek by boosting pass rates from 42% to 93% after just one iteration.
