GopherForge: Go Workbench

A Go compiler, code editor and learning workspace for iPhone and iPad. Build, run, test, vet and format on your device with the bundled Go 1.27.1 toolchain, even offline.

BUILD REAL PROJECTS
• Edit Go and go.mod with highlighting, completion and keyboard shortcuts.
• Follow diagnostics to source lines and inspect per-case test results.
• Import public GitHub repositories, folders from Files or exported archives.
• Navigate nested folders and dependencies; organize projects with tags, favorites and file-name search.
• Download compatible pure-Go modules through the official Go proxy and checksum database. Vendored sources build offline.
• Keep working during downloads, inspect failures and retry from Output. Clear downloaded packages without deleting your source.

LEARN GO
• Follow 169 teaching lessons in 21 units, plus 22 prediction challenges: core Go, structs, collections, interfaces, errors, modules, generics, concurrency and the standard library.
• Read 122 worked lessons, including 19 architecture and eight clean-code lessons, all 23 classic design patterns and six concurrent Go patterns. Compare architecture suitability for tools, domain-rich apps and services with editorial ratings.
• Study Bash, Git, curl, Linux services, Docker, Compose, Podman and Kubernetes with actual commands, probes, scaling and rollback examples.
• Explore twelve MongoDB/Redis readings: shared clients, indexes, atomicity, transactions, cursors, caching, streams and load.
• Packages, modules and tooling now has fourteen teaching lessons covering version graphs, checksums, workspaces, vendor/embed, parallel tests, benchmarks, profiles, build budgets and resource ownership.
• Use 69 original visual guides, 80 design diagrams, practical notes and primary references. Expand highlighted code to full screen.
• Match concepts in Review and work on saved mistakes with three-answer questions and explanations. Progress survives reopening.

PREPARE FOR INTERVIEWS
• Open the separate Interview area: 88 worked guides across 12 topics, from Junior to Staff / expert.
• Explain an answer, compare the reasoning, spot a common trap, solve a worked exercise and tackle a follow-up. Save personal self-assessment separately from lesson completion.
• Cover language/runtime, concurrency, architecture, HTTP/SQL, testing, modules, MongoDB, Redis, Docker/Kubernetes and Go workflows with Claude Code, Codex and Cursor.
• Step through eight algorithms with 24 input scenarios: binary search, two sum, sliding window, BFS, Dijkstra, top-K, merge and dynamic programming. Inspect state changes and read the Go implementations and complexity.

MADE FOR YOUR SCREEN
Collapsible Files, code and results adapt to iPhone and iPad. Supported iPhone Duo layouts respond to display and posture, including code above the fold with keyboard or tools below. Transparent lower scroll edges and extra scroll room keep final lines reachable without inserting source lines. Choose theme, text size, keep-awake during build
