Frontend Engineering at Palantir: Drawing Circles on Maps
On building geospatial tools precise enough for polar operations and missile defense ranges. About This Series Frontend engineering at Palantir goes far beyond building standard web apps. Our engineers design interfaces for mission-critical decision-making, build operational applications that translate insight to action, and create systems that handle massive datasets — thinking not just about what the user needs, but what they need when the network is unreliable, the stakes are high, and the margin for error is zero. This series pulls back the curtain on what that work really looks like: the technical problems we solve, the impact we have, and the approaches we take. Whether you’re just curious or exploring opportunities to join us, these posts offer an authentic look at life on our Frontend teams. In this blog post, Nikita, a Frontend engineer based in DC, shares how rendering accurate circles on maps led him through map projections, spherical trigonometry, and the surpr

Map Widget in Ontology
Hello! I have a dataset deployed to ontology with a geopoint column cast to geopoint type. In Workshop map widget I selected the object layer and set the property to geopoint but no points are showing on the map. What am I missing? 1 post - 1 participant Read full topic
Ontology architecture in Workshop
Hi everyone, We are currently working on designing an ontology architecture in Workshop and would like to get some input and recommendations from the community. Right now, we are debating whether it is better to: use one large denormalized (flattened) object, or keep multiple normalized linked objects that reflect the real relationships in the ontology. Key questions Performance: normalized vs denormalized From our experience, working with many small objects with multiple links and transversals seems to noticeably worsen Workshop performance, especially in dashboards and derived properties. Because of this, we are leaning towards using a single large denormalized object instead of multiple linked ontology objects. Is this a common experience, and is it generally recommended to move towards a more flattened object structure in Workshop to improve performance? If so, what is the practical benefit of maintaining a fully normalized ontology with many linked objects
Displaying aggregation of properties in Pivot Table from not directly linked objects
Hi everyone, I’m trying to create a pivot table in Workshop which displays properties from not directly linked objects. e.g. The link is built in this way A→B→C. Starting with object A, I can only choose properties in A, or add properties in B as derived variables. Is there any way for me to add properties C in the pivot table? 2 posts - 2 participants Read full topic
how to configure multiple egress policies in Foundry
I have a question: how to configure multiple egress policies in Foundry, particularly for scenarios where: External IPs / hosts need to be reached (e.g. ping / connectivity checks), and All outbound traffic must go via a proxy , and We also need to define external host–specific egress policies . Now, it appears we can’t apply proxy-based egress and external host egress policies at the same time. Could someone please advise: Whether multiple egress policies (proxy + external hosts or multiple external hosts) are supported concurrently If there is a recommended pattern or limitation, we should be aware of Any alternative approach to support ICMP / connectivity checks to external IPs when a proxy is mandatory 1 post - 1 participant Read full topic
Speedrun: Your First Agentic AIP Workflow
I’m currently completing the “Speedrun: Your First Agentic AIP Workflow” and I’m blocked at the installation phase of my AIP Logic block (v1.2.0). The Issue: > When attempting to select a model (e.g., GPT-5 nano), the search dropdown is entirely blank. This prevents validation and installation due to inputShapeNotSpecified and PERMISSION_DENIED errors. Troubleshooting Done: Control Panel: AIP is enabled, and the GPT-5 model family is “Enabled” with “Everyone” access. Application Access: AIP Logic is explicitly enabled for my user group. Environment: The model works perfectly in Workshop widgets within the same project, but is invisible to the AIP Logic editor. Project Structure: I have verified project references are added between my working project ( xx ) and the model registry. Is there a specific AIP Service User permission or a Resource Reference I might be missing for the Logic engine specifically? Many thaks 1 post -
Preserve Form Content
I have a function-backed create action and users utilize it via a button in a Workshop app. There are data validation checks in the function (i.e. A + B must equal C for form to be submitted). When a user does not have the condition met the function fails and provides an error message telling the user what they need to fix. However, the form itself is cleared out so the user has to start over from scratch. Are there any options I have to preserve the input form info for the user when an action fails? 2 posts - 2 participants Read full topic
FR: Limit the "addable filters" on workshop
Hey all! We have several objects that have many properties and links degrees of importance depending on which user is looking at them. These objects are used in more than one workshop app with separate use cases. We would like to allow users to add filters to the filter lists we have on each of these apps, but we dont want them to be able to see all available links and properties, only a subset of them that could be relevant to their use case. Would that be something on the roadmap for future development? Is there any workaround that would allow this that I’m not familiar with? Thanks! 1 post - 1 participant Read full topic
Best practices for UX/Design-led application development in Foundry
I’m looking at a project lifecycle where a partner is implementing a core Palantir solution for a client. In these engagements, is there typically a dedicated role for a UX or Product Designer to lead the end-user application design? Specifically, I’m interested in whether teams usually have a designer focused on wireframing and workflow logic in tools like Workshop and Slate , or if that design work is generally expected to be handled by the Forward Deployed Engineers (FDEs) or Application Developers? 1 post - 1 participant Read full topic
Auth failing for Anthropic Agents SDK and LLM Proxy
When building with Anthropic’s Agent SDK (not the client SDK, that works fine) I set the ANTHROPIC_API_KEY and ANTHROPIC_BASE_URL to my Foundry URL and access token. I can see by proxying the requests API calls to my Foundry stack and to Anthropics APIs, for example: [REQUEST URL] CONNECT <REDACTED>.palantirfoundry.com:443 HTTP/1.1 [HEADER] host: <REDACTED>.palantirfoundry.com [HEADER] connection: close [REQUEST URL] CONNECT api.anthropic.com:443 HTTP/1.1 [HEADER] host: api.anthropic.com:443 [HEADER] proxy-connection: close The fill stack URL provided in the is: <REDACTED>.palantirfoundry.com/api/v2/llm/proxy/anthropic The token is a valid token create with the OSDK. I also tried a personal access token. But I keep gettin 401 authentication failed. attempt = 1 error = 'authentication_failed' error_status = 401 max_retries = 10 retry_delay_ms = 536.6033701315846 session_id = <REDACTED> subtype = 'api_retry' type = 'system' uuid = <REDACTED&g
“ExplorationRuntimeNotReady” Error When Exploring S3 Data Connection in Foundry
Hello, I’m encountering an issue when trying to explore an S3 Data Connection in Palantir Foundry. Here are the details: Error Message: Failed to load files Unknown error occurred: STATUS ExplorationRuntimeReadinessService:ExplorationRuntimeNotReady Here’s what I’ve tried: Verified S3 bucket and IAM policies are correct. Confirmed network allowlisting and VPC endpoint configuration. Waited several minutes and retried, but the error persists. Context: I’m in the Data Connection app, attempting to browse files in an S3 bucket. The error appears immediately when I try to load the file listing. Questions: What does the “ExplorationRuntimeNotReady” error mean in this context? Are there any steps I can take to resolve this, or is this an internal Foundry infrastructure issue? Any guidance or suggestions would be greatly appreciated! Thanks in advance. 1 post - 1 participant Read full topic

No preview-transform tool in Palantir MCP?
When I use Continue in the Foundry web IDE, I see the models properly use the transform preview as shown in the docs here: https://www.palantir.com/docs/foundry/palantir-mcp/overview/#build-and-iterate-on-python-transforms However, I noticed that my local Claude Code runs have more issues and it’s because it never previews the code it writes. Claude Code said it didn’t have the tool, and sure enough, the official docs don’t list it either: https://www.palantir.com/docs/foundry/palantir-mcp/available-tools/ Anyone know how to give CC or Codex access to the preview-transform tool like Continue does? 1 post - 1 participant Read full topic

I do not see AIP Document intelligence inside of foundry even though the February 2026 release notes indicate: "AIP Document Intelligence will be generally available on February 4, 2026 and is enabled by default for all AIP enrollments” Is this a bug or when will this be available? 2 posts - 2 participants Read full topic
Accessing PDF via URL in Foundry (works in browser, fails in webhook/pipeline)
Hi everyone, I’m trying to retrieve a PDF from an internal endpoint: Current behavior Works in browser (VPN) and via a button in Workshop Each row in the object table will have its own pdf file that opens through a URL Fails when called from Foundry (webhook/pipeline) → 400 / 503 errors Goal Fetch the PDF Store it in Foundry (media set) Extract text using pdfTextExtractionV1 / pdfOcrV1 What I tried Webhook with OAuth2 → failed (auth / unreachable) Pipeline ingestion → no HTTP/REST connector available Question Is this expected due to network/auth restrictions (browser vs backend)? What’s the recommended way to ingest and process PDFs from such endpoints? 2 posts - 2 participants Read full topic
