In their own words
Port
Port is a cloud-native platform for engineering teams to build, govern, and operate their software development lifecycle. Its platform includes a Context Lake, Software Catalog, Actions, AI Agents, Scorecards, Access Controls, Workflows, and Interface Designer. Port maps environments into the Context Lake and orchestrates agentic workflows across the development lifecycle with governance. It lists 86 integrations in areas such as Kubernetes, CI/CD, incident management, SSO, Git, cloud providers, and AI agents. Examples include Prometheus, Azure Monitor, Rootly, n8n, Claude AI, OpenAI, Cursor, Jira, Slack, ServiceNow, and Wiz. The Free plan has no time limit and includes up to 15 seats, up to 10k entities, up to 400 runs, and community support. Basic is listed at $30 a month, billed annually; paid plans start at $30/user/mo (annual). Port states that it is SOC 2 Type 2 certified, GDPR, ISO 27001, and CCPA compliant, and follows OWASP best practices. It says data at rest is encrypted with AES-256 and data in transit uses HTTPS and TLS 1.2 or later where applicable. User-ingested data is retained until deleted; audit logs are retained for one year by default, and sign-in and account access logs for 30 days.
Signadot
Signadot provides Kubernetes-based sandboxes and validation tools for checking code changes against real services and dependencies. Each lightweight sandbox combines changed workloads with a baseline environment for isolated testing across a microservices stack. A CLI and MCP server connect local workstations to Kubernetes clusters, allowing developers and coding agents to test local changes against those dependencies. Signadot Jobs run Playwright, Cypress, or custom test suites inside Kubernetes and can route tests to a sandbox. Platform teams can define actions in validation plans, which developers can assemble into deterministic validation flows for coding agents. Listed MCP integrations include Claude Code, OpenAI Codex, Cursor, Windsurf, and Zed; other integrations include CI systems, Kubernetes, service meshes, observability, messaging, and workflow tools. Starter is free and includes 50 sandboxes and 100 test invocations per month. Business costs $250 a month and includes 100 sandboxes and 200 test invocations monthly, with a 10% yearly-subscription discount. Sandboxes are billed per creation; a complete test-suite run counts as one invocation. The operator runs in the customer's Kubernetes cluster, while the Dashboard and API run in AWS.
