A side-by-side editorial comparison of Increase and FreeAgent — release velocity, themes, recent moves, and the top alternatives to consider.
A banking-as-a-service API that now sells compliance and blockchain rails, not just payments
Increase ships a quarterly newsletter rather than a running changelog, so each entry bundles a quarter of API work. The last three quarters have moved past core payment rails into the surrounding infrastructure: managed compliance, entity onboarding sessions, 3D Secure, push provisioning and IP-restricted API keys. SDK coverage has widened to C#, PHP and Ruby, and the documentation was reworked to be readable by LLMs.
FreeAgent is expanding beyond freelancers into landlord-specific accounting with automated rental statement processing.
FreeAgent has spent the past year layering Making Tax Digital compliance tooling—early access in September 2025, practice management tools in December, Self Assessment filing for 2025/26 in April 2026. Alongside that compliance track, it shipped a Pleo expense management integration and Fathom analytics connector to round out the financial workflow. The June 2026 launch of FreeAgent for Landlords marks the first deliberate product segment expansion beyond its core freelancer and small-business base.

The arc runs from moving money to operating a bank program end to end. Early quarters added rails (FedNow, Push-to-Card, check transfers); recent ones add the compliance, onboarding and dispute machinery a customer would otherwise build or buy separately. Q2 2026 adds blockchain transfers alongside managed compliance, and flags cross-border payments and lending APIs as next.
Expect the cross-border payments and lending APIs named in the Q2 2026 letter to ship as the next quarter's headline, extending the same pattern of absorbing adjacent financial products into the core API.

The June 2026 launch of FreeAgent for Landlords marks the first deliberate product segment expansion beyond its core freelancer and small-business base.
FreeAgent is running two parallel tracks: deepening UK tax compliance (MTD, CIS, Self Assessment) for existing users, and opening a new market segment with a purpose-built landlord product. Automated rental statement parsing—categorising letting agent statements into structured entries—is the technical differentiator for the landlord track, not just a UI rename. If the landlord product gains traction, FreeAgent's distribution through NatWest's SME banking network becomes a significant acquisition channel.
The next move is likely native HMRC MTD for Property Income submission from within the landlord product, closing the end-to-end compliance loop for landlord customers who currently need a separate tool to file.
