Why F5 Dev

How we're different

Most agencies overpromise and underdeliver. We built F5 to fix that — with the kind of working practices you'd expect from a team that's been doing this for over a decade.

  • 01

    The same people from kickoff to launch

    No account managers, no handoffs, no context lost mid-project. The people you meet at the start are the people who ship your product.

  • 02

    Fixed scope or T&M — your choice

    We work the way that makes sense for your project. Need certainty upfront? Fixed scope. Need flexibility? Time and materials. Both options with full transparency.

  • 03

    Code you fully own from day one

    Source code, infrastructure, documentation — it's all yours. We're a partner, not a lock-in vendor. You can take it anywhere at any time.

  • 04

    Working software over perfect plans

    We deliver in small, frequent increments so you see real progress — not slide decks. By the time we're done, you've been in the driving seat the whole way.
