SaaS platform
Cloud-hosted at app.spanline.dev with a public API, CLI, and workspace-scoped product data.
Company
The engineering workspace for modern software teams
Spanline is an independent software company building a proprietary SaaS platform — one workspace that carries teams from the first inbound webhook through load testing and production operations, with shared identity, organizations, and workspaces.

Independent company
Founded and operated by Tuyn Doan. Proprietary product and codebase — not an open-source fork or reseller.
Shipped capabilities
Capture, Performance (k6), and platform identity are live today; additional lifecycle tools are on the public roadmap.
Built for verification
Marketing site, documentation, status page, and OpenAPI spec are publicly reachable for partners and program review.
Mission
Unify the tools engineers reach for every day
Most teams stitch together a webhook catcher, a load-test runner, and a dozen SaaS accounts. Spanline replaces that patchwork with one product model: organizations own workspaces, workspaces scope environments and evidence, and capabilities share the same session, tokens, and audit trail.
One security boundary
Organization is the tenant boundary. Platform authenticates; workspace is business scope. Roles are explicit — owner, admin, member — with no silent operator bypass.
Evidence over screenshots
Capture sessions, k6 collection runs, and threshold results live in the workspace so reviews, CI gates, and incident response start from the same source of truth.
API-first delivery
Every shipped capability is reachable through documented HTTP APIs and, where it matters, the Spanline CLI for laptop and pipeline workflows.
Product
What we ship today
Live capabilities with published guides. Additional areas — Testing, API Studio, Issues, Releases — appear on the product overview as they reach general availability.
Capture
Disposable HTTP inboxes for webhooks and integrations. Inspect headers and bodies, replay requests, and forward traffic to downstream systems.
Capture guide →Performance
k6 scenarios with live run progress, thresholds, and collection-run evidence. Run from the app or CLI in CI with artifacts uploaded to the workspace.
Performance guide →Platform
Accounts, organizations, workspaces, API tokens, and access policy — the shared fabric every capability mounts on.
Platform guides →CLI
Install spanline on macOS, Linux, or Windows. Run k6 from your laptop or GitHub Actions; results and artifacts land in the workspace.

Leadership
Built by engineers, for engineering teams
Spanline is founded and led by Tuyn Doan, who designs and ships the platform end to end — product model, APIs, and the Spanline web application. The company remains intentionally focused: a single cohesive workspace rather than a suite of acquired point tools.
For partnerships, support, billing, or third-party program verification (including startup and cloud partner reviews), email hello@spanline.dev. We respond from the same domain that hosts this site and the live product.
