Revolutionize Your Data Collection in 2026: The Top 8 Formstack Alternatives to Explore Today!!

Short answer: if you want a privacy-first survey and form builder that doesn't lock core features behind a $99+/month wall, BlockSurvey is the best all-round Formstack alternative. Google Forms wins on pure price (it's free), and Formstack itself is still worth keeping if you're already deep into its native Salesforce workflow and don't mind the cost. Below is a straight comparison, plus 7 other Formstack alternatives worth knowing about in 2026.

If Formstack no longer fits how you work, you have options. Formstack (rebranded to "Intellistack" in June 2025, though the underlying product and pricing structure are unchanged) is a popular form builder and data collection tool, but it isn't the right fit for everyone. The usual sticking points are pricing, restrictive plan limits, and customer support. This post compares BlockSurvey and Formstack head-to-head, then runs through the best Formstack alternatives on the market, so you can find the one that fits your needs.

BlockSurvey vs Formstack: at a glance

Formstack ratings: what G2 and Capterra reviewers say

★★★★☆ 4.3/5 on G2 (470 reviews, Formstack Forms product page). The umbrella "Formstack, LLC" company rating across all its products is 4.5/5 from 1,096 reviews.

★★★★☆ 4.0/5 on Capterra (122 verified reviews)

What to know before using Formstack: a user-review roundup

Across G2 and Capterra reviews, one of the main complaints about Formstack is its pricing. Many users feel the software is overpriced, particularly for small businesses or individuals who may not need all of its advanced features. Pricing is also fragmented across separate products (Forms, Documents, Sign), so costs compound quickly for teams that need the full stack.

Some users also report bugs or technical issues with the software, particularly around integrating with other tools and platforms. That can be frustrating for teams who rely on Formstack for their workflows and data collection.

Customer support complaints are common too: reviewers describe email-only support with slow or unhelpful responses and multi-level ticket queues. Several reviewers also report a difficult cancellation process, with no clear cancel button, a 30-day advance-cancellation requirement, and unexpected or continued billing after trying to cancel. Advanced features (templates, field mapping, complex logic, integrations) carry a steep learning curve too, especially for smaller teams without dedicated admin time. Together, these are the reasons some people give for leaving Formstack.

Why teams leave Formstack

• Pricing compounds fast: Forms, Documents, and Sign are sold as separate products, so a team that needs the full workflow ends up paying well beyond the base $99/mo (or $299/mo for the Suite plan).
• Tight limits on the entry plan: just 1 builder seat, 25 forms, and 1,000 stored submissions per form on the cheapest paid tier. Overflow submissions aren't even stored, they're emailed to the owner.
• No real free plan: only a 14-day trial capped around 2 forms, with no credit-card-free way to keep using the product long-term.
• Support friction: reviewers consistently cite slow, email-only support and multi-level ticket queues.
• Hard to cancel: reports of no visible cancel button, a 30-day advance-notice requirement, and continued billing after a cancellation attempt.
• Steep learning curve: advanced features like field mapping and complex conditional logic take real ramp-up time, which is a burden for smaller teams.

Fair pros and cons: BlockSurvey vs Formstack

Formstack, pros:

• Easy, intuitive drag-and-drop form builder with no coding required
• Strong integration capabilities, including a well-regarded native Salesforce integration
• Powerful conditional logic and workflow automation
• Broad customization options for branding and data collection

Formstack, cons:

• Fragmented, expensive pricing once you need more than the base Forms product
• Restrictive form/submission limits at lower tiers
• Widespread complaints about slow, email-only customer support
• Difficult cancellation and billing practices reported by reviewers
• Steep learning curve for advanced features

BlockSurvey, pros:

• End-to-end encryption on every response, so even BlockSurvey's own team can't read your data
• 1,000+ ready-made templates and AI-assisted question generation
• Advanced logic (skip logic, branching, piping) and white-label branding
• You retain ownership of your data and can export or delete it at any time

BlockSurvey, cons:

• Newer, smaller integration ecosystem than an established player like Formstack
• No native document-signing or full workflow suite (Formstack's Suite plan covers Documents + Sign)

Best for X: the bottom line

Formstack is best for: teams already standardized on Salesforce that specifically need its native Salesforce integration or the combined Forms + Documents + Sign workflow, and who have budget for the $99 to $299+/mo pricing.

BlockSurvey is best for: privacy-conscious teams, researchers, HR, and healthcare-adjacent use cases that want responses encrypted end-to-end by default, full data ownership, and don't want to be boxed in by restrictive submission caps on the entry plan.

8 best Formstack alternatives to consider in 2026 

BlockSurvey

BlockSurvey, is a survey platform built for people who care about privacy and security. If you've been looking for a reliable, secure way to create and manage surveys, forms, and questionnaires, BlockSurvey is worth a look. What sets it apart from other survey platforms is how seriously it treats user privacy.

It also comes with the features you'd expect for building good surveys. With customizable templates, advanced question types, and dynamic logic options, you can build highly personalized surveys tailored to your audience, and you can do it without giving up privacy or security.

Why BlockSurvey is the best Formstack alternative

Strong data privacy:

BlockSurvey puts a heavy emphasis on user privacy and data protection. Your data ownership and identity stay with you, not the platform. Every response is encrypted end-to-end and you hold the keys, which means even BlockSurvey's own team can't read your data. That prevents data breaches, leaks, and the trust issues that follow them, which tends to improve response rates.

1000+ templates:

BlockSurvey has over a thousand free templates you can use to build surveys on the go. You can put together anything from contact forms to online surveys using the pre-made templates without having to write your own questions from scratch. And it's all free, so when you need to quickly spin up a survey, the templates are there.

AI-powered surveys:

BlockSurvey is the only online survey tool that uses AI to help create online surveys. When you need to make a survey but can't come up with the right questions, the AI can suggest questions based on your topic, which helps when you're stuck with writer's block. Let it do the first draft and adjust from there.

Advanced question types and logic:

BlockSurvey offers a range of question types and advanced logic options, so you can build highly tailored surveys. With features like skip logic, branching, and piping, you can create dynamic, personalized surveys that keep respondents engaged.

Complete data ownership:

With BlockSurvey, your responses are encrypted end-to-end before they ever leave the respondent's device, so even BlockSurvey's own team can't read them. You hold the only keys, and you can export, delete, or transfer your data at any time. That gives you full transparency and control over sensitive data.

White-label your surveys:

The white-label feature lets you customize the appearance of your surveys and forms with your own branding, logos, and color schemes. That gives your surveys a consistent and professional look, which helps with brand recognition and credibility.

Customer support:

BlockSurvey offers responsive customer support, so users get the help they need when they need it. From detailed documentation to prompt, friendly support staff, the team is set up to help you get things done. By comparison, Formstack reviewers commonly cite slow, email-only support, which makes BlockSurvey the more reliable choice for getting questions answered.

Pricing and affordability:

BlockSurvey uses a straightforward pricing structure, including a free plan and paid plans. See the current plans and exact limits at blocksurvey.io/pricing. That's a very different structure than Formstack's, where Forms, Documents, and Sign are billed as separate products and the base Forms plan alone starts at $99/mo ($83/mo billed annually).

On privacy, data ownership, and overall value relative to Formstack's per-product pricing, BlockSurvey is a strong Formstack alternative to evaluate. If you want a privacy-first survey platform for your organization, take a look at BlockSurvey and try it for yourself.
