Split Forms

About this app

Split Forms is a hosted form backend. Point any HTML, React, Next.js, WordPress or AI-built form at its endpoint, and every submission is spam-filtered, saved to a dashboard and emailed to you, with no server, PHP or SMTP to run. The free plan includes 500 submissions with no card. It works with forms on sites built by AI tools and has an MCP server (https://splitforms.com/api/mcp) for AI agents.

Scout Review

Written by AI from measured evidence, scored out of 100.

SplitForms is a hosted form backend that does the unglamorous work well: point any HTML, React, Next.js, or AI-built form at one endpoint, and submissions get spam-filtered, stored, and emailed to you. The free plan gives 500 submissions total with no card, Pro is $5/month for 5,000, and Annual is $49/year for 15,000. The docs are genuinely excellent — quickstart, OpenAPI spec, llms.txt, code samples — and the security headers are a clean 12/12. Speed is strong on desktop and good on mobile. Design is polished but has rough edges in the comparison table and a future-dated stamp. Accessibility is mostly there with specific contrast and ARIA gaps. The real story is the pricing wedge: 500 free submissions total versus Formspree's 50/month, and Pro at a third of Formspree's price. For indie developers, freelancers, and AI-assisted builders who just want their form to work, that's a compelling pitch.

Measure by measure

Usability

Docs are a genuine integration reference — quickstart, endpoint, OpenAPI spec, llms.txt. Google or email-code signup, no card, first form auto-created. Pricing table is dense to scan.

Design

Clean, modern landing page with strong orange CTAs and clear hierarchy. Cramped comparison table, generic maker-media graphic, and a future-dated 'Updated October 2026' stamp hold it back.

Speed

Lighthouse desktop 98/100, mobile 85/100 with LCP 2.9s and CLS 0. TBT 412ms is the mobile drag. Marketing pages feel static and light; no lag complaints found.

Security

12/12 security headers: HSTS, CSP, frame protection, Referrer-Policy, Permissions-Policy, SPF, DMARC. HMAC-SHA256 signed webhooks. No SOC 2, ISO, or pen-test claim found.

Accessibility

Lighthouse a11y 93/100. Failing: ARIA role children, color contrast, visible text labels without matching accessible names. No WCAG statement or multi-language support found.

Growth

Improvement areas

Fix the future-dated 'Updated October 2026' text in the hero — it undermines credibility on first read.
Resolve the three Lighthouse a11y failures: ARIA role children, color contrast, and accessible names for visible text labels.

Design & Usability

SplitForms' homepage is a competent, modern SaaS landing page: orange CTAs, a centered signup card, and product screenshots that actually show the inbox and dashboard rather than abstract shapes. The visual hierarchy works — you know what it does and where to click within seconds. The cracks show below the fold: the '30-second answer' comparison table is cramped enough to require squinting, the maker-media card uses a generic dotted-line graphic that feels templated, and a future-dated 'Updated October 2026' stamp in the hero is the kind of detail that makes a careful reader pause. Usability is where SplitForms genuinely shines. The docs page is a real integration reference — quickstart, endpoint spec, request/response shapes, code samples, an OpenAPI 3.1 spec, and an llms.txt for AI assistants. Signup is Google or a 6-digit email code, no card, and your first form and access key are created automatically. The friction is on the marketing side: the pricing table and key-facts box pack too much into too little space, forcing more scanning than the hero ever asks for.

Speed & Security

Speed is a clear strength. Lighthouse desktop scores 98/100 and mobile 85/100, with LCP 2.9s, CLS 0, and FCP 1.2s. The only mobile drag is a 412ms total blocking time, which is noticeable but not painful. The marketing pages feel static and light — no heavy SPA shell, no obvious third-party bloat, and the optional embed.js tracker is explicitly lightweight. No user complaints about lag surfaced in the collected evidence. Security is similarly solid at the infrastructure layer. The HTTP probe returned a perfect 12/12: HTTPS enforced, HSTS, CSP, frame protection, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, plus SPF and DMARC for email. Webhooks are signed with HMAC-SHA256 and have a defined timeout and retry policy. Spam filtering is rule-based with a honeypot, time-trap, per-IP rate limits, and content scoring — no CAPTCHA required. What's missing is the compliance paper trail: no SOC 2, ISO 27001, or pen-test claim appears on the site, which is normal for a product this young but will matter to larger buyers.

Accessibility & Growth

Accessibility lands at a respectable 93/100 on Lighthouse, but the failing audits are the ones that matter: ARIA roles missing required children, insufficient color contrast, and visible text labels without matching accessible names. Those are real, fixable issues, not audit noise. There's no accessibility statement or WCAG conformance claim on the site, and multi-language support isn't mentioned. Keyboard navigation wasn't independently tested, so the picture is incomplete — but the automated signals suggest a site that's mostly accessible with a few specific gaps. Growth is the most interesting dimension. The category — hosted form backends — is mature, with Formspree, Web3Forms, and Basin all established. SplitForms' wedge is pricing and volume: 500 free submissions total (not monthly) versus Formspree's 50/month, and Pro at $5/month for 5,000 submissions versus Formspree's $15/month for 200. That's not a rounding-error difference; it's a structural price advantage. The MCP server with 12 tools for AI agents, plus llms.txt and openapi.json, targets a niche — AI-built and vibe-coded forms — that competitors aren't visibly serving. The domain is only 0.4 years old, so traction is early, but the idea has a clear reason to exist and a specific customer to serve.

Conclusion

SplitForms isn't trying to out-feature Formspree or Basin — it's trying to undercut them while being genuinely pleasant to integrate. The MCP server for AI agents is the most forward-looking piece; as more sites get built by ChatGPT and Claude, a form backend that speaks that language has a real advantage. The gaps are the usual early-stage ones: no SOC 2, no accessibility statement, a design that's 90% there. None of those are dealbreakers for the target customer — indie devs and freelancers who want a form that works without a backend. If you're paying Formspree $15/month for 200 submissions, SplitForms is worth a serious look. If you need enterprise compliance paperwork, come back in a year.
