		Related Products JetBrains Junie Junie is JetBrains' AI coding agent, built to be cost-efficient. It plans with a powerful model and implements with a faster one, so you spend fewer tokens per task while getting the same quality. On the independent SWE-Rebench benchmark, Junie resolves more real-world coding issues than other leading agents, at a lower cost per task. Junie supports the latest models from major frontier labs on day zero, so you're never waiting on integration work to use what just shipped. It works with almost any model you choose, inside IDEs like IntelliJ IDEA, directly from the terminal, or from GitHub and GitLab issues and merge requests. A human stays in the loop. Junie asks for approval before risky actions, and you can redirect it mid-task instead of starting over. Teach Junie your team's coding standards, naming conventions, and review process, and switch from another AI coding agent in seconds with no extra setup. 12 Ratings Visit Website Aikido Security Secure your code, cloud, and runtime in one central system.

Unlike copilots that wait for prompts, Checksum works as a background agent, detecting what needs testing, generating production-ready Playwright, and healing broken tests automatically. Seventy percent of failures resolve autonomously, keeping suites green without manual effort. Built on fine-tuned data from 1.5+ million test runs, Checksum covers every layer of the SDLC: end-to-end, API, and CI testing from a single platform. Tests are delivered as standard Playwright code, submitted as a PR to your repo. No vendor lock-in. Checksum integrates natively with Cursor, Claude Code, and 100+ coding agents via /checksum slash commands, so code is tested before a human ever reviews it. AI handles generation and healing on Checksum's cloud: no LLM tokens. The result: ship faster, with confidence. 1 Rating Visit Website Pensero Pensero is the intelligence behind agentic deployment. As companies deploy AI agents alongside their engineering teams, leaders lose the one thing they need most: an objective view of what is actually getting delivered. Pensero scores every unit of work on the same scale, whether it was human, AI-assisted or agent-only, then shows where each one creates value. That gives you agent performance, cost per unit of work, and agentic transformation, monitored live. Customers call it story points after the fact: an objective measure of what was delivered, comparable across teams, technologies, and any mix of humans and agents. No commits, no hours, no lines of code, no agent activity. Every agent, assistant and human lands in one system of record. Repositories, tickets, chat and AI tools connect automatically, with no instrumentation project and no workflow change. Leaders decide what stays human-led, what gets augmented, and what can be delegated to agents, then optimize that balance against delivery, quality, cost, and business impact. Agent budgets are approved on promise today. Pensero turns them into a portfolio with a return. 3 Ratings Visit Website Haast Haast is the AI engine for marketing compliance.

Shorten cycle time with faster review feedback and high-quality code change suggestions. Your data stays confidential and solely fine-tunes your reviews. The system learns from your interactions, refining the reviews to align with your preferences.	About Open Code Review is an AI-powered code review CLI built from Alibaba’s battle-tested internal code review agent and validated across millions of real-world tasks. It reads Git diffs, sends changed files to a configurable LLM through an agent with tool-use capabilities, and generates structured review comments with precise line-level positioning. Rather than reviewing only the visible diff, the agent can read complete files, search the codebase, inspect related changes, and cross-reference context to uncover deeper issues. Its hybrid architecture separates deterministic engineering tasks such as file filtering, task splitting, rule routing, scheduling, and line positioning from LLM reasoning for risk detection, context exploration, and issue classification. A dedicated reflection module helps intercept hallucinations and knowledge drift before comments are returned. Review depth can be adjusted from low to high depending on the required balance of speed and thoroughness.
