Short version
renmy runtime publishes test-by-test agreement with Salesforce on public projects: 57,634 of 57,636 tests from 132 open-source projects give the same result as on a Salesforce org. Glade publishes full passes on two private repositories. renmy runtime runs on Windows and runs flows and validation rules, which Glade does not list, and adds coverage, mutation testing and an MCP server. Both preview LWC and Visualforce locally. Glade is open source.

| Published agreement with Salesforce | 57,634 of 57,636 tests from 132 open-source projects give the same result on renmy runtime as on a Salesforce org (renmy runtime 1.63.0, measured 2026-10-28). Every project, its commit and every difference is on /parity. | Full passes on two private repositories (12,315 and 782 tests), a diagnostics baseline over 86 public projects, and 475 Salesforce compiler and runtime checks. No per-project test results for public repositories. |
| Engine | Tree-walking interpreter over an ANTLR Apex grammar. Embedded PostgreSQL, with SOQL translated to SQL. | tree-sitter parser, an IR and a virtual machine. SOQL runs in an in-memory executor, with SQLite for persistence. |
| Debugger | Live breakpoints in VS Code and JetBrains IDEs (Pro): conditional, hit-count, log-point, exception and data breakpoints, watches, evaluate and set variable. A recorded run, or a debug log from the org, replays with stepping backwards. | A DAP server, and a parser for Salesforce debug logs. |
| Editors | VS Code extension, its own JetBrains plugin, an LSP server for other editors, and a browser Dev UI. | VS Code integration and an LSP server. No JetBrains plugin. |
| Declarative automation | Triggers, record-triggered and autolaunched flows, platform events, validation, duplicate, assignment and workflow rules, Process Builder, classic approval processes. | Triggers, and since v0.3.1 duplicate and assignment rules. Approval.process runs locally; approval routing requires Salesforce. Record-triggered flows and validation rules are not listed. |
| Standard library | The Apex standard library, including ConnectApi, Slack, DataWeave and the Commerce, Industries and Revenue Cloud namespaces. | DataWeave, ConnectApi and Slack are listed as unsupported. Apex API versions 62.0 to 68.0 only. |
| Test quality | Line and branch coverage, coverage delta against a baseline, mutation testing (Pro), test history and flaky-test detection. | Changed-test and failed-test selection. Code coverage and mutation testing are not listed. |
| CI output | JUnit XML and Cobertura XML with no org (Team). | JUnit and JSON test results, SARIF from glade check. |
| AI coding agents | An MCP server with 18 tools: it runs tests and reports coverage, governor usage, schema and mutation results. Published agent skills. | None listed. |
| Lightning UI | renmy app (Pro) renders LWC components and Visualforce pages locally with no org. A previewed component's @AuraEnabled calls run real Apex, with the standard wire adapters. | LWC and Visualforce previews, labelled as preview features with local-data limits. |
| Platforms | macOS, Linux and Windows. | macOS and Linux. No Windows build. |
| Maintained by | Renmy UG, Berlin. Priority email support on Team, an SLA on Enterprise. | An independent project with one maintainer. |
